The Hills premiered last night, and funnily enough, the party was held in New York.
Mariah Carey was the performer for the evening, singing Touch My Body from her new album, which will of course be on the soundtrack for the show.
Mariah caught a lot of heat for her recent performance on Saturday Night Live, and critics accused her of lip syncing. But she was definitely singing at last night's event, and sounded really good!
