She is said to have married director Taika Waititi in an intimate ceremony in London and has already changed her last name.
But before meeting the New Zealand director, 46, Rita, 31, enjoyed a string of high-profile relationships with actors, singers and even TV stars, writes Dailymail.
The "Hot Right Now" singer's most serious boyfriend was Calvin Harris, whom she dated for a year in 2013, before it was learned that her relationship had ended.
Like Calvin, she ended up in the headlines for her many relationships with famous names, including: Rob Kardashian, singer James Arthur, Andrew Garfield and Travis Barker.
In the following, we introduce you to some of her most sensational relationships over the years:
Bruno Mars 2009 - 2011
Before either of them achieved fame, Rita dated Bruno Mars at the age of 18, later saying: "It was love at first sight."
"We met in 2009. I was 18 years old and I started working at 'Roc Nation'. Bruno was unknown even then," she said.
"He was a composer hired to compose songs for me. I thought, 'Wow, this is the greatest man in the world!'" Ora said.
But unfortunately, as their careers took off, their romance fell through the cracks and they ended up breaking up.
She continued: “Our time together was wonderful. But once we became famous, work got in the way. We finished it last year. But we stayed close. And when we were together we were very happy", Rita declared.
Rob Kardashian - 2012
The singer dated Keeping Up With The Kardashians star Rob for two months before the former couple ended their short-lived romance due to their 'busy work schedules' and incompatible lifestyles.
And she admits she forgot she was dating the Kardashian sisters' brother because their relationship was 'very short-lived'.
The end of their short romance coincided with a series of bitter social media posts from Rob, who indirectly suggested that the singer had cheated on him numerous times during their relationship.
He tweeted: “When a woman cheats on you with a man, I can live with it. People make mistakes, trust me. I have forgiven him many times."
"But when a woman disrespects herself by messing around with more than 20 men, all while in a relationship with a faithful man," he wrote.
"I just don't understand how a woman can do this to her body. And your career hasn't started yet. I can't stand teasing. Loyalty", he concluded.
James Arthur - 2013
X Factor winner James said he first met Rita after she asked him out on a date in 2012 and claimed they ended up together on her bus.
The 34-year-old singer claimed that there was a strong connection between them that led to a passionate romance.
He wrote in his autobiography, titled Back To The Boy: “There was a lot of magic there and it was an amazing night. Rita seemed really, really into me, but I still couldn't believe it."
"Rita and I met up a few more times after that and had some more wonderful nights. 'I'm in love with you,' she told me one night. She said it so honestly that I wanted to believe it, even though it sounded crazy," the X Factor winner said.
But James claimed that one day she simply 'disappeared' and he knew it was over when he saw her photographed with other men. "I was heartbroken. It hit me really hard," he said.
He later admitted that he had 'sabotaged' their romance due to his 'low self-esteem', telling This Morning: "You have to like yourself, love yourself. I'm beating myself up, I don't have a lot of self-esteem. That was probably the main issue."
Dave Gardner - 2013
Rita Ora enjoyed a one-night stand at Dave Gardner's London home in February 2013.
After spending the evening at the football agent's house, the (then) 22-year-old singer walked out the front door on Tuesday morning, looking a bit sore, wearing the same clothes and shoes as the night before.
A source told him Dailymail at the time: “Rita seemed to be in a very flirtatious mood. She was the life and soul of the party and was talking to everyone."
Reports also say she spent most of the evening flirting with Dave as the pair got to know each other.
Neither commented on the meeting.
Calvin Harris - 2013 - 2014
Calvin and Rita tied the knot in the spring of 2013 – their relationship lasted about a year.
DJ and Rita had a romantic and professional relationship, collaborating on Rita's hit song, titled "I Will Never Let You Down".
The Scottish DJ took to social media to announce that the couple's year-long romance had ended, but it was claimed that the "I Will Never Let You Down" hitmaker was unaware that her boyfriend was about to make the announcement.
Rita has previously said that things 'got weird' when he composed the song "I Will Never Let You Down" for her - a song which took Rita to number one in the UK charts.
"It was more of a thing where I was in awe. I was at that point in my relationship where I felt like he could do no wrong. I thought he had my back and that he would never steer me wrong," she told Marie Claire Magazine.
“But then 'I Will Never Let You Down' came out and it all started to go a bit weird. I don't know if it was because professional life was mixed with personal life or what," she declared.
Rita added: "There was a reason why I broke up with him. And there was a reason why I'm at this point in my life where I feel like I have so much musical freedom and I don't have to explain myself to anyone."
After their breakup, Calvin reportedly 'banned' Rita from performing the song at the 'Teen Choice Awards' that August, and she also lost the right to perform it at many concerts.
Ricky Hill - 2014 - 2015
Rita and Tommy Hilfiger's son, Ricky Hil, confirmed his relationship with Rita in August 2014, only to split up 14 months later.
They got together the summer after she broke up with Calvin.
The decision to end their year-long relationship was said to be 'mutual' although neither have commented on the news. Rita was busy filming The X Factor at the time, while Ricky, a hip-hop artist and son of designer Tommy Hilfiger, was staying in America.
A$AP Rocky - 2015
Rocky had a fling with Rita in 2015. The rapper later sparked controversy when he included explicit lyrics about his rumored ex in his song "Better Things."
ASAP - whose real name is Rakim Mayers - later admitted that his comments about Rita were 'tasteless'.
"I'm not looking at it like 'it's bothering me,' because I'm not really against it," Rita told Radio Station Hot 97. "I think about it and I don't want people to think it's okay to talk about women like that . This is it."
She added: “I don't care what you say about me. It is, but you know you have to keep it moving. I am very satisfied with what I do and I am proud of who I am and what I represent."
Rocky later admitted the text was 'tasteless', and while Rita hadn't heard of his response - she said it was 'good' that he accepted it.
Travis Barker - 2015
Rita had a brief one-month relationship with Kourtney Kardashian's current husband in the fall of 2015.
Travis reportedly ended the relationship at the time due to not wanting to be in a 'serious relationship'.
Andrew Watt - 2016 - 2017
Rita enjoyed a year-long romance with fellow musician Andrew in 2016 before splitting, with the star revealing her single status during an appearance on The Jonathan Ross Show.
Andrew Garfield - 2018
The singer and Hollywood actor dated for four months before Andrew called time for a 'more private life', with Rita returning to Watt's arms for a brief reconciliation after her split from Garfield.
Actor Andrew and Rita reportedly started their romance in late 2018.
But in March 2019, it all came to an end with a friend telling the tabloid The Mirror: "The relationship just broke down. It's sad, but they've both accepted the situation and moved on."
The "Girls" hitmaker was first linked to the actor in 2018 after they were spotted walking side by side in London.
Romain Gavras - 2020 - 2021
The French director, who is based in London, started dating Rita after her split from Andrew.
The pair enjoyed a whirlwind romance during their brief relationship with exotic holidays in Ibiza and Corfu.
In October 2020, the pair fueled rumors of a possible engagement when Rita was spotted with a large diamond in her ring.
A source close to Rita told her Dailymail said of their split: "Rita and Romain tried to make it work, but they both agreed it wasn't meant to be."
"They remain close, but it was simply impossible to maintain a relationship where they barely saw each other."
"And given their busy schedules for 2021, there was no way it could continue."
Rita and Romain split weeks after her infamous birthday party in November 2020, when she broke the UK's anti-COVID rules.
A media spokeswoman for Romain, 39, confirmed to Dailymail: "Rita and Romain split months ago due to difficulties with their respective work commitments. They remain close friends."
Taika Waititi - 2020 - ongoing
The couple started dating in March 2021 after meeting in Australia and were said to be moving so fast in their relationship that they started discussing marriage within months, a source told New Idea.
The "Lonely Together" hitmaker and the "Thor: Love And Thunder" director, 46, have both been photographed with gold rings on their ring fingers in recent days - sparking speculation that they had already consummated their romance.
