The singer, whose brother is Backstreet Boys star Nick Carter, was recently eliminated from Dancing with the Stars and he got another shock when he found out he owes the Internal Revenue Service a whopping $1,010,635 in unpaid taxes dating back to 2003.

“It is unfortunate that while Aaron was a minor, his finances were grossly mismanaged by his previous team which has lead to the current situation of which he was unaware of until today,” says Johnny Wright, Aaron’s manager. “Aaron is working with a new team to take appropriate actions towards speedy resolution of the matter and looks forward to putting this behind him and moving forward with the next stage of his music career.”

The former pop singer — who was recently eliminated from ABC’s top-rated ballroom competition Dancing With The Stars – has been slammed with a staggering $1 million tax bill from the Internal Revenue Service.

According to TMZ.com, papers filed in Los Angeles Superior Court on Monday show the star owes $1,010,635 to the U.S. government.

Aaron and his professional partner, Karina Smirnoff, just missed out on next week’s Dancing With The Stars semi-finals round, but managed to gain acclaim from judge Len Goodman, who addressed the pop star with an emotional speech.

“I think the dedication that you have shown week after week is absolutely fantastic. You’re an inspiration to all young people that anything is possible and if you were my son I would be so proud of you,” Len told Aaron. “But more important, you be proud of yourself, because you’ve been great.”

“One thing I will always remember and take from this competition is the lessons I learned,” Aaron said to the judging panel. “I’ve grown so much with your compliments and your criticism, so thank you for helping me be able to grow on this show.”

A rep for the singer tells The Insider that the crooner injured his knee this afternoon during rehearsal with his partner Karina Smirnoff. While medics tried icing Aaron’s bum knee, he may not dance on tonight’s show.

Aaron is the latest of several competitors on the ninth season of Dancing With The Stars to suffer series-related injuries; former House Majority Leader Tom Delay and Entourage star Debi Mazar have also been injured in rehearsals for the show in recent weeks.

Drug-addicted former teen icon Aaron Carter will join the cast of Celebrity Rehab with Dr. Drew when the hit reality drama returns for a second season on VH1 this Fall.

“Aaron has a terrible marijuana problem, and he’s no longer being offered much work. At least by appearing on VH1, he will be back in the spotlight and get used to being in front of the camera again. And hopefully he can get sober at the same time,” an unnamed spy spilled to The National Enquirer.

“He made good money as a teenager, and when he turned 18, he got access to $2.7 million- before he knew it, it quickly was being whittled away.”

Aaron will join a cast including former Hollywood Madame Heidi Fleiss and rocker Sebastian Bach.
