Aaron Carter Shows Off 30-Pound Weight Gain In Shirtless Photo After Spending 14 Days In Rehab

Aaron Carter, best known as the younger brother of Backstreet Boys' Nick Carter and a successful singer himself, opened up to his fans on September 22, 2017, and let them know that he'd be heading off to rehab.

He had previously appeared on episodes of The Doctors, where he was very candid about his addiction. "I've been to multiple psychiatrists, multiple therapists, but nothing has ever helped me and truly worked the way that this is starting to and this show is starting to," he said on an episode.

On that same episode, a 911 call was played that was made by a friend who said Aaron was "on the verge of death" and needed help. Thankfully, Aaron accepted an offer of attending rehab for treatment of his drug problem.

Aaron took to social media to let his fans know he'd be seeking treatment and had checked into a rehab facility for two weeks.

While the singer said he wouldn't be back online until 2018, he surprised fans by posting a new photo of himself looking healthier and happier — and 30 pounds heavier!
