In a clip from the star's upcoming episode of WE tv's "Marriage Boot Camp: Family Edition", Aaron talks about his difficulties growing up in the spotlight and again brings up the comparison between himself and the "Sorry" hitmaker - causing his mum to retaliate and shoot down his argument.
"I was doing tour after tour after tour after tour," the singer is heard lamenting, before Jane interjects: "I don't think it was that much - you weren't a Justin Bieber".
"Thank you," Aaron fires back. "That means a lot. I'm no Justin Bieber. I'm a piece of s**t. I'm a piece of s**t. I paved the way for that kid".
However, Jane soon gave in to her son's point of view, agreeing when he suggested the "I Don't Care" singer copied his hairstyle, adding: "He copied everything about you".
But despite feuding with Justin for almost a year over the similarities between the pair, the "Aaron's Party" singer appeared to have a change of heart on the matter, considering: "No, guess what? I am no Justin Bieber. I am Aaron Carter".
The embattled pop star is currently in a bitter dispute with his brother Nick, with the Backstreet Boys musician filing for a protection order against his sibling, claiming Aaron harboured thoughts of killing his wife and then unborn daughter. Aaron's twin sister Angel Conrad later requested a similar restraining order.
The troubled singer denies the allegations, insisting his family is trying to "control" him.
"Marriage Boot Camp: Family Edition" debuts 11 October.
