What were those rumors about Robin Wright Penn catching Sean Penn in bed with some Russian models?

Not that it has anything to do with this, but… Sean Penn has been out in public with 28-year old Czech model Petra Nemcova for the second time in just two days. The second appearance was the most visible — they showed up at Elton John’s Aids Foundation Oscar Night party together!

So are they officially a couple now? We’ll have to ask Joy Bianchi what the buzz in the room was when she comes back. She was at the Elton John party, too (and looking totally chic, no doubt.)
