In town to host a party at the Clarendon Ballroom this evening, a muy plumpo Perez Hilton swung by Hot 99.5’s radio station this a.m., then hit a few hot spots in the District. He even said that he and his spies saw Nicole Richie in Georgetown, which would be kind of weird — and Big Head DC’s sources can’t confirm it yet — but whatever. Even if she was there, her whereabouts still was not the most sizzlin’ spot in Washington today. That distinction has got to be reserved for Perez’ sweaty armpits! Peee ewwww.
