Celebrity transformations are nothing new - but we're bowled over by these stars' new looks.
Christina Aguilera is a style chameleon. We've seen her sport everything from leather chaps and two-tone braids to old Hollywood glam.
But the singer is now unrecognisable. Appearing on the front cover of Paper magazine, the 37 year old is makeup free with her freckles on show.
In an interview with the publication, Christina says she's not going to ditch her makeup anytime soon and explained why she loves changing her appearance:
"I've always been someone that obviously loves to experiment, loves theatrics, loves to create a storyline and play a character in a video or through stage.
I'm a performer, that's who I am by nature. But I'm at the place, even musically, where it's a liberating feeling to be able to strip it all back and appreciate who you are and your raw beauty."
Another celebrity who looks radically different these days is Peter Andre. The popstar, who's known for his squeaky clean image, has transformed into a heroin addict for a film role.
The Australian is starring in new short independent film, The Inheritance. The 45 year old's been spotted on set in Los Angeles with tattoos, piercings and track marks.
