Charlize and Sean Can't Keep Their Hands Off Each Other

Charlize Theron and Sean Penn showed PDA when they arrived in NYC on Sunday after catching a flight out of LA. It isn't clear why the duo, who went public with their romance in January, are in town, but it might have something to do with Monday night's Met Gala, which will draw A-list celebrities and the fashion elite to the Metropolitan Museum of Art. Neither Charlize nor Sean are on the rumored list of attendees, but, seeing how Charlize has a close relationship with Dior, it wouldn't be out of the ordinary to see her at the event. Meanwhile, Charlize also has a big project to promote in the coming weeks, as her new film with Seth MacFarlane, A Million Ways to Die in the West, will hit theaters on May 30.
