Young Buck's been subject to many roasts at the hands of 50 Cent. With Buck's new project on the way, 50 Cent took an unorthodox route in raising awareness for it on social media.

"Young buck is almost ready to drop his album. He worked hard on this project, I told him his personal choice to date a tran sexual will confuse some of his core audience but with the support of the LGBT he should be fine," 50 Cent wrote on Instagram, reminding everyone of Buck's alleged affair with a transgender person.

Buck caught wind of the topic and threatened to "Ja Rule" the Power executive's career on Instagram Live.

Young Buck dished out a response to 50 Cent for his comments earlier today. Buck called out Fif for not only trolling on social media but also for his shady business practices that have left the former G-Unit member tied to a contract. He also threatened to destroy Fif's career, saying, "I'll burn your career down. I'll Ja Rule you."

"I thought you was 50 Cent... I thought you had some real n***a tendencies," Buck said on Instagram Live while waiting for his flight to take off. "You a real life sucka, n***a," he added before claiming 50 Cent's trying to manipulate the fans with unsubstantiated rumors. "If you such a real n***a, why don't you let me go? You understand what I'm saying? And we'll fight the battle like that," he continued. "Line me up like Ja Rule. Go bar-for-bar with me, n***a. Play that game, you scared?"

Buck also seemed to suggest that he has some dirt of Fif that he's willing to dish out if the feud continues. Considering that he was once good friends with Fif, it doesn't seem far fetched that Buck might have some tea to spill on him.
