An ITV star looked unrecognizable as she posed in a Billie Eilish-style green wig while filming new scenes.
The actress traded in her signature blonde hair to transform into pop star Billie, 20.
But it was of course Emily Atack under the shiny hair and the green glasses – on set for The Emily Atack Show.
Emily, 32, shared the snap on her Instagram story, even showing her posing in the same style as Billie.
It comes after The Sun revealed the former star of The Inbetweeners is in the running to host ITV’s Big Brother reboot.
We talked about how Emily was in the mix with the likes of Vick Hope, Roman Kemp, and original Big Brother host Davina McCall.
A source said: “Emily and Vick have become the favourites.
“A huge list has been put together with a number of big name stars including Davina.
“However, there is a feeling that bringing in a new face would be good for the reboot.
“Emily is already part of the ITV2 family with her work on Celebrity Juice.
“Vick is a great interviewer and would bring a younger audience to Big Brother through her work on Radio 1.
“Roman also had interviews and made the shortlist.
“Rylan Clark is another name in the mix but like Davina he has worked on Big Brother before.”
