PENN BADGLEY

Their relationship may struggle on Gossip Girl, but in real life, Badgley and Blake Lively's romance is going strong. The twosome even appeared in a pro-Obama ad together last fall. Although they remain tight-lipped about their romance, their costars are only too happy to voice support. "They're both darling and very together as people," says Kelly Rutherford, who plays Lively's mom, while Matthew Settle, who plays his dad, said of the "very hot" couple, "I think they're good for each other."
