Gerard Butler Parties At Madonna's On Oscar Night

Move over, Jen. There's another hot blond who may want your man!

Madonna and Gerard Butler would certainly make quite the pair - as they're both famously sexy flirts. These two perfect matches found each other last night - and spent Oscar night getting down at Madonna's afterparty, according to someone who was there.

Gerard attended a private bash that Madge, Demi Moore and producer Guy Oseary threw in the Hollywood Hills March 7 - and despite the very late hour, the action was steamy, we're told. Madonna and Gerard were "all over each other," one eyewitness tells HollywoodLife.com. "She was putting on the full-court press, totally charming him - and even challenged him to a dance-off! They were grinding in the middle of the room real close and then Demi joined in. It was hot! Gerard was loving the attention."

After their sexy dance display, Madonna, 52, and Gerard, 40, huddled in a corner - but alas, she left alone.

Well, thank God Jen Aniston wasn't there to witness THAT display, we say. The 41-year-old Bounty Hunter star was probably doubly glad she didn't hit the party, given that another of her exes was there. No, not Brad Pitt - but Bradley Cooper, who tore up the dance floor with his girlfriend, Renee Zellweger. "They were so cute," adds our eyewitness. "After they got off the dance floor they ran to take their picture together in a photo booth."

That's that for couples - but we also have to give out an award for the coolest parents on earth - which should definitely go to Demi and Lenny Kravitz. "They dragged (Lenny's daughter) Zoe and (Demi's oldest) Rumer on to the dance floor and partied in a big dance circle while guests were cheering them on," says the spy, who adds that even Lenny's ex, Lisa Bonet, was in on the action. "It was quite the scene."

We'll say - Taylor Lautner even made an appearance! Now THAT is how you know it's a party!
