The tangled web of Sienna Miller and Lindsay Lohan competing against each other in Hollywood is about to turn professional.
The two stars have shared boyfriends - at different times - like Jude Law and Jamie Burke. And now Lindsay is once and for all completely replaceable by Sienna.
The stylish starlet has signed on to take over Lindsay's role in "The Best Times Of Our Lives," after the 20-year-old backed out of the production.
Sienna will now join British starlet Keira Knightly in the film... and some steamy sex scenes.
Lucky for Sienna, who has had her fair share of love scenes and semi-naked photo shoots, Keira also doesn't have a problem with getting in the buff on film.
Oscar nominee Keira recently said, "Sex scenes are easy. I don't really have a problem with them. Actually it's quite liberating in the movie 'Domino' to be out in the middle of the desert completely topless with a beautiful Venezuelan guy. I was very lucky."
Lindsay Lohan, meanwhile, is starring as a stripper in "I Know Who Killed Me."
