Happy birthday wishes are in order for America's favorite fast swimmer (he's just slower at everything else), Ryan Lochte! The Olympic gold medalist rang in his 28th year at Planet Hollywood in London, because, duh, where else would this dreamboat go to party, right? While Lochte is currently single (and not sleeping around -- that's not how the Lochte household defines "one night stands," okay?), he did tell E! News that he's interested in settling down. "Yeah, I mean I definitely want a relationship. I want to give a certain someone my heart," Lochte said. "I mean, I just gotta find the right girl." I'm sure there are many ladies willing to make themselves his birthday gift.
