50 Cent and Young Buck are exchanging shots once again.

On Wednesday, Fif shared an Instagram post that sarcastically promoted Buck's next studio album, suggesting it would be a hit among the LGBT community.

"Young Buck is almost ready to drop his album," 50 wrote. "He worked hard on this project. I told him his personal choice to date a tran sexual [sic] will confuse some of his core audience but with the support of the LGBT he should be fine [...]"

50, who founded Buck's label G-Unit Records, was referencing Buck's alleged sexual relationship with a transgender woman, which Buck has consistently denied.

Shortly after 50's transphobic post, Buck took to Instagram Live to call out the G-Unit boss with several threats and a challenge.

"You’re trying to sabotage me, pull my music down, send cease-and-desists everywhere, put up little posts and jokes for laughs while you do weak ass shit behind my back and try to keep me tied to a contract," Buck said in the broadcast. "If you such a real n***a, why don’t you let me go? You understand? And we’ll fight the battle like that. Whatchu scared for, sucka? Line me up like Ja Rule, n***a. Go bar-for-bar with me, n***a. Play that game. You scared? You wanna do sucka shit. You ain’t gonna get away from me though."

Buck went on to say that as soon as he gets out of his G-Unit contract, he'll unleash on his former friend and collaborator. Buck also suggested he had dirt on 50, and threatened to ruin the rapper's career by exposing his deeds.

"We gonna tell them the truth if we're gonna play this game. We ain't gonna sit here and do this. Tell 'em what you're really doing," Buck said. "Tell 'em you got your panties in a bunch 'cause I'm tryin' to move forward with my own career. We not gonna talk about all the other shit, unless you want to. Understand what I'm sayin'? [...] We gon' get real. I can blow your shit up, n**ga. For real, for real. I'll burn your career down. I'll Ja Rule you."

Fif has yet to respond.
