Emily Atack looked completely different as she transformed into Katy Perry for the latest episode of Celebrity Juice.
The 32-year-old comedy actress donned a long purple wig and ice cream mini dress for the segment, which she teamed with neon pink platform heels.
Sharing preview snaps from her dressing room with her 1.8 million Instagram followers, Emily struck a number of sultry poses – including one with a giant yellow and pink lollipop.
She captioned the California Gurls themed post: “Welcome to the Keith and Katy UK tour.”
Emily’s pal and co-host Laura Whitmore also dressed up, slipping into a white hooded jumpsuit as Kylie Minogue in the Can’t Get You Out Of My Head video.

Filming for the new series of Celebrity Juice is currently underway and will air on ITV later this year.
But team captains Emily and Laura – who took over from Holly Willoughby and Fearne Cotton – regularly share behind-the-scenes snaps on social media.
The pair were seen boozing in the green room with Celebrity Juice host Keith Lemon.
They also shared videos of themselves twerking backstage as Keith showed off his dad dance moves.
Emily shared that in the very first episode something very unfortunate happens – but viewers will have to wait to find out how.
Posting a snap of her and Laura holding glasses of vino, Emily said: “Show one DONE. What a night. Covered in dog food.”
Emily, who also has her own comedy series The Emily Atack Show, says landing the Celebrity Juice job is a dream come true for her.
She said: “Everything I’m doing now is my kind of dream job.
“I would say Celebrity Juice is a real pinnacle for me, because it’s one of the bigger shows on television.
“Stepping into shoes like Holly Willoughby’s is the most ridiculous and daunting path as a telly person. It’s like, ‘How on earth will I fill shoes like that?’
“But I’m just so humbled and flattered – and I’m so glad to be doing the show with Laura. She’s my really good friend.
She added: “The great thing about Juice is it’s one of the few shows where you can actually have a drink on the telly, let your hair down, laugh at really naughty things and just be a bit of a teenager again.”
