Pop star Willow Smith fell victim to a hacker Wednesday (March 24), who took control of her Twitter page and wrote unsavory posts about Chris Brown. A suspicious tweet was posted to the 10-year-old's social networking account, which commented on Brown's spastic behavior following his appearance on 'Good Morning America' earlier this week.

"So Chris Brown is going to prison now breaking a window at ABC, but he didnt go for hurting Rihanna? #karma," read the post on Smith's Twitter page. The tweet was later removed and replaced with an explanation, posted by the singer's record label, Roc Nation. "This is a negativity free zone, unfortunately this account has been hacked thanks for your support. Sincerely @rocnation."

As previously reported Brown went ballistic on the show after being asked questions, by journalist Robin Roberts, regarding his infamous assault on Rihanna back in 2009. Despite attempting to steer the questioning towards his album release, Roberts pressed on with more questions, before backing down. The 21-year-old then went to his dressing room and reportedly broke a window, before leaving the studio and appearing on the New York City streets shirtless.

Brown has since apologized for his behavior noting that he was "disappointed" in his actions and got "very emotional."

His fourth album 'F.A.M.E.,' hit stores Tuesday (March 22), and is expected to top the Billboard album charts.
