Incarcerated rapper Mystikal's hopes for an early release from prison have been dashed by a Louisiana parole board. The "Shake That Ass" hitmaker, real name Michael Tyler, was sentenced to serve six years at a prison in Homer following his 2003 conviction for sexual battery and extortion.

He was found guilty of forcing his then-hairstylist to perform oral sex on him as he videotaped the incident after the female employee allegedly stole $80,000 from him.

Mystikal recently applied for an early release, but that has been turned down.

The hip-hop star is staying positive about his career setback, however, and is reportedly putting his time behind bars to good use.

A source tells AllHipHop.com, "Mystikal is in great spirits, despite the parole board's decision not to release him. He's been writing and focused on his career once he is finally released."

Mystikal is now likely to remain in prison until 2010.
