Rita Ora is feeling just like a rockstar.

The “Girls” singer got into the Halloween spirit by dressing as Post Malone. And she went all out with her elaborate costume, which came complete with facial tattoos, a grill, curly brown locks, sleeveless denim jacket, cigarette, and Post’s favorite accessory, a bottle of Bud Light. She donned the uncanny resemblance during KISS’ Haunted House Party at SSE Arena, Wembley in London on Friday (Oct. 26).

“Ima get Halloween started for you the right way… postttyyyyyy I LOVE YOU BRO @postmalone…ratatatatataata wassssss gooood!!” said the 27-year-old Ora.

Fans barely recognized her when she and her dancers hit the stage to Malone’s “rockstar.” She also performed her own singles “Your Song” and “Let Me Love You” while in costume. “What the fuck is good HALLOWEEN 2018 @postmalone i LOVE you bro,” she added. “Surprised Wembley as you tonight at my show my fans didn’t even recognise me LOL.”

The costume was met with rave reviews on social media and from her peers including Katy Perry, who wrote, “YOU WIN 2018 BB…I AM OBSESSED WITH YOU.”

Ora is gearing up to release her sophomore album Phoenix on Nov. 23 featuring the single “Girls” with Cardi B, Bebe Rexha, and Charli XCX, plus appearances from Liam Payne, Rudimental, Julia Michaels, and the late Avicii.
