Hey, guess who's dating Petra Nemcova? I'll give you one guess, it's not you. Or me. Boooo. Actually, Petra Nemcova and Sean Penn are the hot new Hollywood couple, according to Page Six, and according to these pictures of the couple taken last night as they went from Post-Oscar Party to Post-Oscar-Party.

Newly single Sean Penn and supermodel Petra Nemcova slipped out of LA's Villa nightclub at 3:10 a.m. this morning -- clearly Hollywood's hottest new item.

The pair followed up an appearance at a CAA event two days ago with a full-on assault of coupledom tonight at Elton John's Oscar Party (above). Sean, 47, and Petra, 28, posed on the red carpet at the singer's AIDS Foundation fete and danced to his many hits before heading to Villa.

Now, what I really need to know is what the hell it takes to date a Supermodel. I was told that having a blog, and constantly making fun of celebritis was good enough, but clearly someone lied to me.
