Singer Aaron Carter has checked back into rehab on Saturday, October 14 to resume his treatment. Following a two week break he took to attend to "legal and personal matters," the singer has returned to Rehab and is focused on completing the 90-day program prescribed to him, Us Weekly reported.

Just last week, the performer took to Twitter to share a photo of himself, flaunting his 30-pound weight gain. He wrote in the now deleted post, "Needed some time to heal and this is a direct result." Carter was visibly healthier than he was when he appeared in an episode of "The Doctors" where he publicly admitted that he was struggling with prescribed medications and his overall mental and physical health.

Singer blames his 'stressors' for deteriorated health

Back in September, Aaron Carter wrote an emotional note on Twitter, explaining his decision to enter rehab to further improve his mental and physical health. According to E! News, the singer wrote that he was "disappearing for awhile to work on myself," but will continue to release music this month.

On October 27, Carter will release a new version of "I Want Candy," his hit from 2000. He also said, "I'll see you soon looking amazing" and claims that he will be ready to perform for his adoring fans. The singer admitted that "my stressors haven't subsided with family and this year has been crazy and I need some time off from all of it."

Performer has a feud with brother, Nick Carter

Back in July, Entertainment Tonight reported that Aaron Carter called out his brother, Nick Carter, for using such a public platform (Twitter) to reach him after his DUI arrest.

Carter said, "Nick made no efforts to call me, and he knows how to reach me." While Nick took to Twitter to say that he was there for his little brother and that he was "willing to help" him get better.

Aaron was upset about the tweets and said that there's "too much animosity" between the two brothers.

He asked, "Why wouldn’t he call me directly and have a conversation instead of making this about him through a very public forum?"

Nick Carter's wife responds

According to Nick Carter's wife, Lauren Kitt Carter, Aaron changed his number again, which was why they could not reach him. However, Aaron insists that his older brother would know how to contact him.

This isn't the first time the brothers have been in a public feud, as footage from their reality TV series "House of Carters" always showed the two fighting. Whether or not it was all for the cameras, however, remains a mystery.
