3 weeks after the jet crash that claimed 4 lives, Travis Barker is still in the hospital.

"I am doing the best I can possibly be," he said in the magazine's latest issue. "I'm so anxious to get out of here. ... I've just been in surgery after surgery. I have third-degree burns basically from my feet up to my waist and both hands. One of my hands has second-degree burns and one has third-degree burns."

Barker was released from a Georgia hospital last week and is now being treated at a burn center in Los Angeles. He said he was too afraid to fly cross-country, so he arranged to travel by bus with his father and ex-wife Shanna Moakler to keep him company.

"I'm trying to have a quick recovery and play the drums again and be able to hold my kids again," said Barker, who has two children, Landon, 5, and Alabama, 2, with Moakler.

If all goes well, Barker expects to leave the hospital within two weeks.
