Lauren Conrad looked great in a little black dress by Foley + Carina when she attended the White House Correspondents’ Association dinner. She can still smile and look beautiful even with Spencer Pratt still insisting – this time on The Tyra Banks Show last week – that he’s “100% sure” that there was indeed a Lauren Conrad sex tape.

Really, I think the real reason Heidi Montag and Spencer Pratt hate Lauren Conrad so much is because she’s so much more successful. Not to mention prettier.
