Although there was no pre-existing feud between Justin Bieber and Aaron Carter, hints of one was detected when the former subtly dissed the latter in a tweet Wednesday.

"Aaron carter I had your album when I was little. And bumped the song Aaron's party. I was like 7. if you need a hype man I got you,” Bieber tweeted.

The context behind the “Sorry” singer’s comment was a series of tweets from Carter where he whined about not being given enough credit for paving the way in the music industry for young artists like Bieber.

When a fan tagged Carter, making a statement like, “It's been explained to me why @AaronCarter never reached the level of success @justinbieber did, but I still wonder about it,” it struck a nerve with the “I’m All About You” singer.

“Listen man. I can’t sit here & just not say anything to that, I’ve been in this industry before he was born. I’ve had harder times and always bounce back. No I’m not Justin Bieber I’m Aaron Carter. I’m also in construction I paved the way. These kids have NEVER paid me homage,” Carter replied to the fan.

In a separate tweet, he continued his rant. “Why don’t you try losing everything and having the professional world turn their backs on you including your fans, gain their respect back and then never give up on yourself and get back at me. Maybe I’ll have some advice for you,” he said.

According to Celebrity Net Worth, while Bieber has a net worth of $265 million, Carter's net worth is negative $2 million.

The song Bieber references to in his tweet, was from Carter’s second album, "Aaron's Party (Come Get It)" that sold over three million copies in the United States alone. His debut album was in 1997 and was certified Gold in Canada, Denmark, Germany, Norway and Sweden. His third album, released in 2001, also went platinum.

Although Carter was a huge pop and hip-hop sensation back in the 1990s, appearing in teenage TV shows such as “Lizzie McGuire,” “Sabrina the Teenage Witch,” and “7th Heaven,” his popularity gradually faded away as the new millennium approached.

He filed for bankruptcy in 2013 in the state of Florida, listing his monthly income as $2000, against an average monthly expenses of $2005. As per the filing, his total assets – including a $500 television, two MacBook computers, a Louis Vuitton backpack and a $3500 Breitling watch – was valued at $8232.16. Apparently, he owed the Internal Revenue Service (IRS) $1.368 million.
