Singer Aaron Carter has checked into rehab again.

Carter’s enrollment comes ahead of his custody hearing for his 9-month-old son, Prince.

“It’s an abstinence program and I work with an individual counselor,” he shared.

“I do group therapy, parenting classes, domestic violence classes,” the singer added.

The artist also admitted that quitting marijuana was his primary motivation for enrolling.

The musician shared that his ability to maintain sobriety resulted from growing up and being a parent.

Carter shares Prince with his fiancée Melanie Martin.

The pair are fervently pursuing joint custody of their child again.

"I want my son back. That's the headline right there,” Carter said.
