Southern rapper Young Buck isn’t backing down from his boss. Buck Marley has responded to shade fired his way from G-Unit head 50 Cent.

YB went to Instagram this week and hinted at having a bombshell to drop on Curtis Jackson.

On Wednesday, 50 jumped on Instagram with posts aimed at Buck Marley possibly getting dissed by a transgender person.

Last month, Fif jumped on Instagram to troll YB about his past rumored connection to an alleged transsexual woman.

In a recent SiriusXM interview, the Unit’s Tony Yayo discussed where things stand with Buck following recent transgender romance rumors.

“I don’t even know what’s up with that, man,” Yayo said when asked if Young Buck is still in G-Unit. “Buck is a spontaneous dude, you never know what to expect from him. Me, myself, I didn’t step on his neck while he was down because of all the tranny allegations. Transgender. Let me not say ‘tranny’ and people come looking for me – I just feel like in your career, your life is an open book and it was a situation it was out there. I didn’t know how to respond to that. I just remember the last time he had a gay accusation and he called me and I said don’t even worry about it, it’ll breeze over. It’s just press. 72 hours in this world, it’s over. 48 hours, 72 hours it’s a wrap. But this time I didn’t know what to say to him about the transsexual woman. To each’s own. 50 clowned on him a little bit. 50’s crazy. You know how he do. But everybody was clowning. I feel like in that situation, you can’t just get mad at 50 because the whole world was clowning you at that point. Every website. TMZ. Worldstar. Then you was on the phone with the person. N*gga, you on the phone again? Come on, n*gga, stay off that phone.” (SiriusXM)
