Oscar-winning actor Sean Penn has turned to a familiar support system now that his actress wife Robin Wright-Penn has kicked him to the curb for the final time — ex-wife Madonna!

The volatile pair, who were married from 1985-1989, reconnected after having cocktails at New York’s Greenwich Hotel last November and have remained on good terms ever since.

Madonna, who divorced hubby Guy Ritchie earlier this year, has been helping Sean, 49, through the latest in series of fallouts with Robin, In Touch Weekly claims on the pages of its Sept. 14 issue. And although she’s currently dating 22-year-old Brazilian model Jesus Luz, sources say a reunion could be on the horizon for the Hollywood exes who famously co-starred in the 1986 stinker Shanghai Surprise.

“Madonna still considers Sean her soulmate,” her friend tells In Touch. “It’s highly possible that she and Sean will somehow get back together now that they’ll both be divorced.”
