Mon dieu, what has Marion Cotillard done to her face?
Well everything can just calm the hell down, because the actress is only donning a pair of prosthetic lips for her new role in celebrity satire Rock'n Roll.
The Oscar-winning star shared a series of selfies which showed her posing with a very plumped up pout on her Instagram page, prompting fans to freak out and wonder what she had done to her mouth.
Cotillard plays a more cosmetically enhanced version of herself in husband Guillaume Canet's meta showbiz comedy, which he wrote, directed and co-stars in as himself.
The film sees Canet on the verge of a mid-life crisis when a younger co-star tells him he's not rock'n roll any more, and can't sell movies.
So in an attempt to prove them all wrong, he employs the help of his girlfriend Cotillard, who appears to be in crisis too, if her selfies are anything to go by. It also features Hell or High Water's Ben Foster and Johnny Hallyday.
The couple previously teamed-up for critically-acclaimed ensemble drama Little White Lies and Franco-American thriller Blood Ties.
The Le Vie en Rose star is currently expecting her second child with Canet. She most recently starred opposite Brad Pitt in World War II drama Allied, and Michael Fassbender in action adventure Assassin's Creed.
Rock'n Roll was released in France last month.
