Rapper Tee Grizzley‘s not only mourning his friend, PnB Rock … he’s also got drama at home after burglars made off with $1 million in bills and bling.

Law enforcement sources tell TMZ … burglars smashed a window at Tee’s house about 2 weeks ago in his Porter Ranch neighborhood outside Los Angeles. We’re told the jewelry alone they found was worth more than a mil, and they also walked away with a ton of cash.

According to the police report, no one was home at the time of the break-in, and there’s an open investigation.

Tee’s havin’ a rough time these last few weeks — as you know, PnB was shot and killed Monday while eating lunch at a Roscoe’s Chicken and Waffles. The murderer, who’s still on the loose, stole several diamond chains off the rapper.

Tee released the music video for part 4 of his “Robbery” series the day after Rock’s death, opening with a “Rest In Heaven” message for PnB.

FYI, the track has nothing to do with Tee or PnB’s situations … it’s a fictional story he’d been working on before either incident happened.
