Sean Penn and Petra Nemcova are back on — four years after splitting!
Last week the couple were spotted holding hands during U2 lead singer Bono's birthday party at the Spotted Pig in New York City, and they left together, according to Us Weekly.
The pair dated for a weeks after ending the courtship in February 2008.
Penn hasn't been romantically linked to anyone since splitting from Scarlett Johansson last June, but Petra didn't waste any time pursuing Sean: She called her off her engagement to British actor Jamie Belman just last month.
"Petra started going on dates with Sean right after the split," a source tells Us.
