Aaron Carter checked into rehab a day after police showed up to his home for a welfare check. His publicist explained in a statement on Friday: “Aaron has decided to enter a facility to improve his health and work on his overall wellness. He is going to do this privately and focus all his attention on being the best person and performer possible.” Police had arrived at Carter’s home Thursday after getting a call that he seemed to be “under the influence of something” from a person who had previously been on the phone with Carter and “felt something just wasn’t right.” Cops were also called to his home earlier this month for another welfare check, and in July, Carter was arrested on DUI and drug charges with his girlfriend. On Friday, he tweeted, “Only I can change my life. No one can do it for me.”
