Blake Lively and Penn Badgley (both wearing Ralph Lauren) stick together on and off camera and off. Here they are seen at the Nina Ricci afterparty at the Met's Costume Institute Gala Monday in New York.

While the Gossip Girl stars don't admit they're dating, Penn Badgley told People regarding Blake Lively, "I think she's incredible. She's an amazing person and she's beautiful - so there's not a lot to dislike."

Don't Penn Badgley and Blake Lively make the cutest couple?
