Jay Rock was promoting his new album 90059 on Power 106's The Lift Off when he got a call from a fawning female fan. Or so he thought.

She told him she loved the album. "Man, I appreciate that, baby," Jay said.

Then the caller tried to get his number, and said she liked them "Tall, dark and handsome." Rock took the sexual aggression in stride.

But suddenly the voice on the line got deeper. It was no lady, but rather Jay's Black Hippie bro Kendrick Lamar getting his prank call jollies.
