Aaron Carter was reportedly “gone” for a long time before his death.

His friend and O-Town lead singer, Erik-Michael Estrada, is shedding light on Carter’s behavior prior to his November 5th death.

According to the singer, Carter “distanced himself from everyone” before his untimely passing.

Estrada recently appeared on the “Behind the Velvet Rope” podcast and explained his friend was “gone” for a long time before November 5th.

“The sad part is with Aaron is that he had been gone for quite some time, right? Like, even though he was still here, he wasn’t,” Estrada admitted.

“He had distanced himself from everyone, and he made it very clear that he didn’t want anything to do with a lot of people who really cared about him.”

Estrada and Carter came up during the boy-band era and grew to be close friends.

However, their friendship began to breakdown as Carter’s mental health declined and substance abuse increased.

“But he had demons, and he had issues that he was dealing with, and maybe some trauma, and obviously some mental illness,” Estrada shared.
