Gwyneth And Madonna's Falling Out

They’ve been dear friends for quite some time, but rumor has it Madonna and Gwyneth Paltrow have called it quits on their friendship.

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

Though Madonna's rep denies the "breakup," an Us magazine source tells that things went downhill slowly for the duo after Madonna split from Guy Ritchie in 2008, leaving "Gwyneth and Madonna with less in common." (Paltrow's been wed to U.K.-born singer Chris Martin since 2003.)

Both Madonna and Paltrow have had falling outs with friends in the past. The “Material Girl” singer and Sandra Bernhard broke things off in 1991, while the “Shallow Hal” actress and Winona Ryder had a falling out in 1998.
