Jay-Z's "D.O.A." has raised the ire of T-Pain and the singer has openly said, "F**k Jay-Z according to rapper Fabolous.

"Yo I'm at Rehab (club) in Vegas.. T-Pain is DJ'ing.. Sayin F**k JayZ, he old, blah blah.. guess its backlash from D.O.A," Fabolous said on his Twitter account.

T-Pain heavily relies on the Autotune technology, which was the topic of Jay-Z's "D.O.A. (Death of Autotune)." The song was the lead single on Jay-Z's Blueprint 3, which is to be released on Tuesday.

Fab continued to tell what he was doing an also offered his opinion of T-Pain's shot at Jay-Z.

"So I'm here wit Rihanna, @richyungamerica, & @paulcainsf.. Drinkin some strawberry/daquiri's.. Not feelin the Tpain JayZ dissing.. Brooklyn!"

Ironically, the person that DJ'd after T-Pain immediately started to play "D.O.A." and then a full set of Jay-Z song, Fab revealed.

Fab said that T-Pain was still in the club during the Jay-Z set.

This is the first time that T-Pain has expressed this level of disenchantment with Jay-Z. Ea rlier this summer T-Pain joined Jay-Z on the stage during Hot 97's summer. He seemed pleased with the recognition in an earlier interview with MTV.

"That affected me in a great way, man. I made sure I honored him as a great song writer...that's like the best song i heard in a couple years, man. And it's great that somebody that important stepped up and vouched for me."

T-Pain has not commented on the matter at press time.
