Actor Josh Hartnett celebrated his return to full health on Thursday night with a wild party.

The Black Hawk Down star was released from Los Angeles' Cedars-Sinai Medical Center earlier this month, five days after he was admitted suffering a gastrointestinal disorder. And the star proved he is back to his normal self on Thursday - with a boozy night out with pals at the Florida Room in Miami's Delano Hotel.

A source tells People.com, "Josh jumped on stage with a local Miami band. He looked happy and was having fun."
