Sean Penn's past dance card includes the likes of Madonna and Robin Wright, but now he can add Charlize Theron to that dance card, because he's confirmed in a recent interview that he & the Oscar winner are all boo'ed up!

According to E! News, Piers Morgan was the first to confirm that this A-list couple is now official. "I walked over to Sean's table, where he was sitting with new girlfriend Charlize Theron," Morgan writes. "'I'm so glad you two have got together,' I said, 'Sean's a great guy,"' he added of his exchange with the Oscar winning actress. "'I know,' she smiled, putting her hand round his shoulder. At 2 a.m., Sean came over, and bear-hugged me ... 'Congrats on a great night,' I said. 'And congrats on Charlize too.' He laughed. 'She's a keeper, that's for sure...well, I'll do my best to keep her anyway!'"

According to The Huffington Post, Theron has a respectable dance card as well -- best known for her long-term relationship with Stuart Townsend, the South African beauty also dated Third Eye Blind frontman (and the world's biggest self-important douchebag) Stephan Jenkins and actor Craig Bierko. She also has an adopted son, Jackson, who is 2. "Penn's ex-wife, Robin Wright, recently got engaged to her boyfriend, actor Ben Foster. She and Penn have two children together, daughter Dylan, 22, and son Hopper, 20," reports The Huffington Post.

And even though the couple has been together for a few months, Morgan's spotting of the pair was the first time that the couple had not only been spotted in public together but also confirmed their relationship. Even though they walked the red carpet separately, they had no problem showing off their affection once they were reunited inside the event.

So do you think that this couple -- unlike many other celebrity couples -- will actually have staying power? Or do you think this is a rebound? Leave your thoughts in the comments below!
