Las Vegas, cupcakes and Avril, oh my!

Avril Lavigne celebrated with The Palms owner George Maloof - and a cupcake from The Cupcakery! - at Moon nightclub in Las Vegas after her sold-out show Tuesday night at The Pearl Concert Theatre. After 90 minutes of singing, unfortch, Avril lost her voice! She even let us know by writing it on her hand: "I can't talk - lost voice."

We hear you had to postpone your concert in SD tonight... get better, Avril, you don't wanna disappoint your fans!
