HARTNETT BACK TO FULL HEALTH

The Black Hawk Down star was released from Los Angeles' Cedars-Sinai Medical Center earlier this month (04Apr09), 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."
