Aaron Carter is showing off some progress with his health a month after entering rehab.
People reports the "I Want Candy" singer crowed on Instagram of his newfound health, "This is my before and after pics. I went from 115 to 160 pounds in two months I feel amazing. 2018 I'm ready for you!"
He also promised his fans new music.
Carter had previously called his thin frame the result of a hiatal hernia, a condition with which he said he'd been diagnosed at age 19.
Earlier his year, Carter and his then-girlfriend were arrested on DUI and drug possession charges. The two later split, at the same time Carter came out as bisexual.
