At the celebration for her birthday at the Los Angeles hot spot, LAX, Heidi Montag decided it would be a good idea to perform for the crowd. And by perform, I mean, she danced around goofily, while lip-synching to her own first single, while her dorky boyfriend Spencer Montag played hype-man and Perez Hilton nodded in agreement awkwardly. It’s hilarious, yet sort of uncomfortable. Sort of like watching someone’s parents trying to freak each other at a wedding. In any case, here’s the happy couple and unsuspecting guests before the event, everyone smiling, not yet aware that later in the evening, they’ll be forced to take home a gift bag, having had lied through their teeth that why yes, Heidi’s single was AWESOME and they can’t WAIT for the video, where there’ll be plenty more dancing.
