Chris Brown has been sprung from the big house ... the pokey, the pen, the clink, the cooler, the joint, the bastille, the lockup, the ... .
Anyway, the singer is out after 108 days in jail, according to TMZ. He was sentenced to 131 days on May 9 for violating his probation related to his 2009 assault of Rihanna. He had received credit for a stint in rehab and previous time in jail.
Speaking of that probation violation thing, Brown still faces trial for allegedly assaulting a 20-year-old man in October outside a Washington, D.C., hotel.
