Lily Allen Parties Like a Rock Star!

British pop star Lily Allen is just beginning to make waves in the states, but she's already got the bloody rock star lifestyle down pat.

With her Courtney Love training wheels on, the 21-year-old took the stage at the South by Southwest Music Festival in Austin, Texas on Wednesday -- with a cigarette and a bottle of beer in hand. *burp*

Looks likes Lily's music isn't the only thing getting the good buzz!
