47-year-old actor Sean Penn, recently separated from his wife of 11 years, Robin Wright Penn, set tongues wagging last night, making the Oscar party rounds with 28-year-old supermodel Petra Nemcova.

The two arrived together at the Elton John AIDS Foundation screening party, separated briefly for interviews, photos, etc., then reunited for some understated PDA.

Nemcova, who claims she and Penn are just friends, split from crooner James Blunt early last year, and is the new face of Rampage Jeans.
