Guy Ritchie MADONNA102707_01_X17.jpg Madonna may have spent the weekend away from both her husband Guy Ritchie and her wedding ring - but that doesn't mean she's been far from Guy's mind!

The Daily Mail reports that Guy has been quietly planning an extravagant party for the Material Girl's 50th birthday. Sources close to Ritchie claim the director's plans are "well advanced", although invitations have yet to go out.

"He's going to push the boat out," a friend told the Daily Mail. "He's given it a lot of thought."

Ritchie has been arranging the party for early August in between finishing up RocknRolla, his latest flick. The guest list stretches to 200 invitees including friends and family of all kinds.

One guest who won't be attending, however, is Sir Elton John, whom friends claim Madonna still hasn't forgiven for accusing her of "miming" on her last tour.

Friends of Ritchie claim that the party should nip all the rumors of an impending divorce directly in the bud.

"This is hardly the action of a man about to be divorced by his wife," a close friend says.

Guess there's only one way to know for sure!
