In the wake of Aaron Carter’s shocking death, those in his inner circle are airing some grievances.

Aaron’s longtime friend, Gary Madatyan, expressed how he wished Nick Carter would’ve “done a little more” for his younger brother.

In the same breath, Madatyan also revealed his friend had an “obsession” with the Backstreet Boys singer.

“I wish he [Nick] could have done a little more as a blood relative to Aaron,” Madatyan told Page Six.

I’m not judging him. I’m not saying anything bad because I respect him,” Madatyan continued.

He claimed, “Aaron had an obsession with his brother.”

Nick acknowledged they had a “complicated relationship” in his social media tribute to Aaron.

Prior to his untimely death, Aaron and Nick were working on their relationship.

A rep for Aaron said that he and Nick were in a “good place” prior to his death.
