Rita Ora and her husband dressed up as Zorro and Elena for Halloween night

Rita Ora and her husband, Taika Waititi, joined a large group of famous faces who climbed aboard the mechanical bull at the Halloween party hosted by Vas J Morgan and Michael Braun in West Hollywood on Thursday night.

The evening brought together a host of celebrities including Paris Hilton, 43, Rebel Wilson, 44, and her wife, Ramona Agruma, who headed to the private Country and Western-style mansion for the special bash.

Singer Rita, 33, had chosen to dress up as the character Elena from the film Mask of Zorro, with a sword in hand and a tight white bodice and long skirt, writes Dailymail.

Meanwhile, Taika, 49, looked impressive in his role as the masked avenger created by American writer Johnston McCulley.

The guest list included names like Kaia Gerber, Hailey Bieber and Cara Delevingne, while organizers Vas and Michael spared nothing to give the party a special atmosphere.

Rita, always up for a challenge, lifted her skirt and climbed onto the back of the bull next to her director husband.

At one point, she playfully held a sword at her partner recreating the famous tension between Catherine Zeta-Jones' character and Antonio Banderas in the 1998 hit film Mask of Zorro.

But Paris chose to stay grounded as she greeted her friends from the sidelines.

The socialite took inspiration from an early friend of hers for the costume, recreating one of Britney Spears' most iconic looks for the spooky occasion.

The heiress wore an outfit similar to Britney's famous outfit in the 1999 music video ...Baby One More Time, with a short white shirt and gray school skirt, paired with patent platform shoes.

Meanwhile, Rebel and his wife Ramona, who christened their love in Italy last month, wore matching cowboy outfits and posed before mounting the bull.

The Australian actress wore a fringed Western jacket and straight jeans for the festive vibe. /Telegraph/
