Now B.o.B. is jumping into the ring to share his two cents regarding Kendrick Lamar's verse on 'Control.'

On 'How 2 Rap,' Bobby Ray fires back at Kendrick for not being named as one of the great lyricists.

"My first mixtape, they all said I sounded like Dre [Andre 3000]," B.o.B. spits. "Then they said my album was pop, didn't really sound like the mixtape / Now I'm doing what I started, now they telling me I changed / I hear underrated so much, you would swear it was my name / Ain't no rappers on my list / Come holla at me when you're done riding each other's d---."

On Monday night, Big Sean debuted 'Control,' which also features Jay Electronica, on DJ Funkmaster Flex's Hot 97 radio show. While props were given to those two for their efforts on the track -- the song was originally to appear on Sean's 'Hall of Fame' album -- Kendrick's verse is the one that caused an uproar on social media.

The Compton, Calif., native made claims such as he's the "king of New York" and the "best MC." New York rapper Joell Ortiz also responded to his verse with his own song.
