Incarcerated R&B singer Chris Brown has been sentenced to a further 131 days in jail after admitting to violating his probation.

24-year-old Brown told an LA court that he had been in a fight in Washington D.C. last year which violated the terms of his probation relating to his 2009 attack on then-girlfriend Rihanna.

The ‘Loyal’ singer has been behind bars since March for leaving a court-ordered rehab facility.

Superior Court Judge James R. Brandlin sentenced Brown to 365 days in jail, but also gave him credit for the 234 days he has already served.

A recent court report on Chris Brown revealed that he has been ordered to attend therapy twice a week to address his bipolar and post-traumatic stress disorders. He must also submit to random drug testing three times a week.

Despite his time in prison, Chris Brown continues to appear on the music of other stars including Usher and Arianna Grande.
