Chris Brown’s upcoming album, “X” may be his last, according to the singer himself. The 24-year-old, who is known to vent via social media site Twitter, posted a series of cryptic messages Tuesday morning.

“Don’t worry mainstream America. After this X album, it’ll probably be my last album,” he wrote, before continuing to say, “Being famous is amazing when it’s for ur music and talent [sic]. I’m tired of being famous for a mistake I made when I was 18. I’m cool & over it!”

It seems Brown was referring to the incident in 2009 when he beat up then-girlfriend Rihanna , leaving her with visible bruising and scrapes on her face and what looked to be bite marks on her body. His career took a nosedive for a number of years as fans labeled him a woman beater. In interviews following the attack, most reporters continued to focus on the beating instead of his music and other projects he was promoting at the time.

Though Rihanna, 25, eventually got back with Brown, it was not until years later, and they have since had a tumultuous on-and-off again relationship.

Last September, Brown was criticized again when he got a facial portrait on his neck that was speculated to be of Rihanna. The black-and-white image shows a woman with a bone structure strikingly similar to that of the Barbadian beauty. Her lips are covered in stitches and she looks like she has a black eye and bruising on the right side of her face. He later denied that it was her.

Brown’s album, “X” will be his sixth studio album and is out in stores Aug. 20.
