As friends and family rush to Augusta, Georgia's Joseph M. Still Burn Center to be with [article id="1595303"]Travis Barker and DJ AM[/article] (born Adam Goldstein) — who are recovering from serious burns they suffered in a plane crash on Friday night — thoughts and prayers continue to pour in from other friends and peers, such as Paul Wall, the Game and Yung Berg.

Producer Jermaine Dupri visited Barker in the hospital on Sunday, according to UsMagazine.com, and said that though the situation was very serious, the former Blink-182 drummer was doing well.

"It's a seriously sad situation," Dupri said. "He's doing good ... but I really hate to see my friends go through this."

Barker's ex-wife, [article id="1595305"]Shanna Moakler[/article], flew in on Saturday, and AM's former girlfriend Mandy Moore was also spotted at the burn center on Sunday. An unnamed source told TMZ.com early Monday that AM is "ambulatory and in good spirits."

While Barker is best known as part of the punk-pop band Blink-182, his formidable drumming and production skills have earned him deep respect from the hip-hop community, thanks to his energetic beats on remixes of songs by Soulja Boy Tell'em and Flo Rida.

Speaking on Cincinnati urban radio station 101.1 the WIZ on Saturday night, Yung Berg paused to send out condolences to those killed in the crash and best wishes and prayers to Barker and AM. [article id="1595307"]Fall Out Boy, Beanie Sigel, Lindsay Lohan[/article] and other celebrities have also sent out messages over the weekend.

The Game also weighed in, telling AllHipHop.com that he was "deeply hurt" by the news of the deadly crash. "Travis Barker has always been there for me when I needed him creatively. We've done many songs together," the Game said. "Just recently he appeared in my video ['Dope Boyz'] that he featured on. I respect and love him. My prayers are with him and his family in this difficult time for his speedy and complete recovery."

Barker is also close with rapper Paul Wall, with whom he formed an all-star group called Expensive Taste. "It's so shocking and unexpected. Travis and AM are such generous people. They would literally give you the shirt off their back," Wall told AllHipHop. The rapper also commented on Chris Baker, one of four people killed in the crash, saying, "And Lil Chris was such a great friend. He was down for life. I feel so bad for his wife and son that are going through such a hard time right now. Family is something very important to Travis and Chris. We all gotta pull together right now."

As of Sunday, AM and Barker were still in critical but stable condition after the crash, which officials say may have been caused by a [article id="1595313"]blown tire[/article]. Doctors said that they suffered second- and third-degree burns but are expected to recover fully. Barker sustained burns on his torso and lower body, and AM was burned on his arm and head. An official at the hospital said that neither sustained any other physical injuries, but they could be hospitalized for weeks.

"Anybody who can survive a plane crash is pretty lucky," Dr. Fred Mullins, medical director of the Still Burn Center told reporters during a news conference Sunday morning.

Killed in the crash were pilot Sarah Lemmon, 31; co-pilot James Bland, 52; Barker's assistant and close friend Chris "Little Chris" Baker, 29; and security guard Charles Still, 25.

In addition to friends and family, The Associated Press reported that several fans visited the hospital over the weekend. "I was just shocked when I first heard it, and I knew that I had to do something," said Ryan Meadows, a 19-year-old college student from Augusta.

A statement from the families of both artists thanked fans and friends for their support. "The families wish to thank fans from all over the world for their prayers and concern," the statement read. "Deepest sympathy is expressed to the loved ones of those who perished in the crash."
