On Thursday, Funkmaster Flex got on his Hot 97 radio show and blasted Jay-Z in an epic rant. (You can listen to it below, he really gets going at the ten minute mark.)

Flex continued his rampage against Jay-Z yesterday, posting on Instagram what he says is a new text message from Jay which reads "This is HOV." Flex then wrote this message to Jay-Z in the caption:

"Really? After calling private for hours you texting with CAPITAL letters????? This guy thinks it 1997 ???? Tomorrow 7pm I got this???? I see you need a tune up and lesson in respect!!!!!."

So it seems like Flex is going to go in on Jay-Z -- who may have been trying to contact Flex -- again on his radio show tonight. Flex is also heavily involved in the Dipset reunion, and the group just dropped the freestyle 'Victory,' which takes aim at Jay-Z.

Is Hov going to have to respond to this stream of disrespect, or can he just sit back and let his dollars do the talking?

Really? After calling private for hours you texting with CAPITAL letters????? This guy thinks it 1997 ???? Tomorrow 7pm I got this???? I see you need a tune up and lesson in respect!!!!!
