After last Friday’s devastating plane crash that killed four people and critically injured DJ AM and Travis Barker, Jermaine Dupri says his friend Barker is doing well.

“He’s doing good, he’s gonna be alright. He’s just got a lot of healing to do,” Dupri, who visited the former Blink 182 drummer in the hospital last Sunday, told PEOPLE exclusively Thursday night.

Dupri, who was celebrating his 36th birthday at Chicago’s The Underground Nightclub after attending a concert by girlfriend Janet Jackson, said that Barker is also doing well emotionally.

“He’s supposed to send a message out to everybody in a couple of days to let everybody know that he’s feeling better,” he said. “He’s definitely feeling the love from everyone.”

Customized Room

Barker’s improved spirits could be due to his newly outfitted hospital room: “He’s just now getting everything in the hospital set up for him – iPods, computers, everything that he needs,” says Dupri, who estimates Barker will be in the hospital another two weeks. “You got to make sure he is comfortable.”

The music producer – and Barker’s partner in the So So Def clothing line – said news of the crash put him in a state of shock. “I was at home, somebody called me early in the morning,” he recalled. “It was kind of crazy and I didn’t really comprehend what had happened.”

Yet he says he has no doubt his friend will fully recover. “I think everything will be cool when I get back there [to see him]. He’ll probably be up and talking crazy and all that – back to his old self.”
