Travis Barker photographed outside recording studio following hospitalization

Even a stay in the hospital isn't enough to keep Travis Barker away from the music.

People obtained a photo of the Blink-182 drummer leaving his Calabasas, California recording studio Tuesday, exactly one week after he was first admitted to the hospital with what he called "severe life-threatening pancreatitis."

Also on Tuesday, Barker tweeted, "7 days in the hospital," seemingly suggesting that he'd been discharged. He added, "Grateful for so much."

Meanwhile, Barker's also been getting back to business on his Instagram, posting Stories teasing upcoming collaborations with blackbear and renforshort.
