Rapper 2 Chainz, fresh off a guest spot on '2 Broke Girls,' was arrested for possession of marijuana in Maryland last night  on Valentine's Day.

Cops pulled over a white van in which he was traveling at 10 p.m. He had weed on his person, so he was arrested. He was the only person in the vehicle taken into custody.

He was booked and eventually released. Standard stuff, right? It was, until the po po, who must be fan boys, asked for a photo with him! We know this since 2 Chainz posted about it on Twitter.

Chainz also denied having weed on him. Instead, he had paraphernalia – a grinder, which crushes up the herb so you can smoke it.

Just another day at the precinct...
