DJ AM in Hospital!

According to TMZ, Nicole Richie has been spotted entering and leaving St. John's Hospital in Santa Monica over the past five days. But it isn't Richie who is in need of medical attention -- it's her on again, off again boyfriend, DJ AM.

Richie's man has been at the hospital for the past several days following up on gastric bypass surgery, a procedure he had in 2003. Richie has been at his side almost every day, spending hours a day at St. John's. When we called DJ AM's publicist Nicole Chabot for a comment, she said he was there for a "standard" follow up. "He's doing fine," she said.

UPDATE 1:55PM ET -- Perez Hilton is reporting that AM had 20 pounds of excess skin removed and then spent several days recuperating at Serenity, where Star Jones also recovered after her recent surgery.

This story could be possible the last time we saw DJ AM was with Nicole and Mischa at the pottery place on April 19, 2006 haven't seen a picture of him since Click here to view those pictures.
