Today is Demi Lovato‘s 19th birthday … and she kicked off the celebration last night by hitting up a local grocery store for a case of beer with her presumably-over-21 friend.

Lovato went to rehab last year, but her people said it was not for drugs or alcoholrelated issues.

For her part, Lovato tweeted last night, “Birthday redbulls cause #soberissexy… Duh. :)”

This doesn’t look good Demi!
