After more than a decade of friendship, Gwyneth Paltrow is taking a holiday from Madonna. "Everything always revolved around Madonna," a source close to the Iron Man 3 star, 40, tells Us Weekly. "She is finally done."

Waiting in the wings to replace Madonna, 54? Cameron Diaz! "Gwyneth is a nurturer," a source says of Paltrow, who has been pals with Diaz, 40, for years, but recently upgraded her to BFF status. The Bad Teacher star "is bummed about being single, so Gwyneth sees her as a project."

Find out more about why Paltrow dumped the Material Girl -- and how she aims to find Diaz a man! -- in this week's Hot Stuff video, as explained by Us Weekly Senior Editor Ian Drew, plus special guests Liz Marguiles and Angela Pham from Bravo's Gallery Girls.
