A TMZ reporter caught up with Boosie Badazz in New York City on Thursday, June 1, and asked him if he'd record a song with Gunna for a billion dollars.

Gunna, of course, has been rap's public enemy number one since being accused of snitching on Young Thug and YSL in a RICO case.

At first, Boosie didn't want to answer the question about working with Gunna.

"I don't want to talk about a rat," he said.

Boosie then compared Gunna to the rats in New York City.

"I see about three Gunnas right now," he pointed out. "One just went under the sewer."
