Madonna & Gwyneth Paltrow: Mom's At War!

A source close to Madonna, 51, and Gwyneth Paltrow, 37, say the dear gal pals, BFFs since 1999, are dunzo.

"They don't speak," says the insider. "I can't tell you exactly why they had the falling out, but Gwyneth can be jealous and competitive."

Although Madonna's rep denies the "breakup," the source says things went downhill slowly after Madonna split from Guy Ritchie in 2008, leaving "Gwyneth and Madonna with less in common."

And to be sure, both women have a history of bagging their besties: Madge fell out with Sandra Bernhard around 1991; Paltrow cut ties with Winona Ryder in 1998.

In fact, Paltrow (who once called the singer "like an older sister") hinted at a new feud in May's British Vogue: "I'm having a situation right now with a friend where I'm feeling pretty angry."
