Young Buck is once again coming for his former label boss and G-Unit bandmate, 50 Cent.

Following the conclusion of their long-running financial dispute last year, Young Buck shared a since-deleted post on Instagram that showed various pictures of the Playboy Mansion in Los Angeles, as well as some alleged blueprint screenshots that showed tunnels under the property. “‘You worried about tellin LIES’ but the TRUTH is Hollywood gets weird,” wrote Buck alongside the post. “What went on at the mansion #50Cent Curtis??? The internet be LOUD… But them mansion nights be QUIET.”

There’s been a long-running conspiracy theory that there are “tunnels” under the Playboy Mansion. The screenshots that Buck shared appear to be fake and could be traced back to a 2015 April Fools joke Playboy shared, which has since been deleted. One of Playboy founder Hugh Hefner’s former girlfriends, Holly Madison, addressed the conspiracy theory in an interview on the Talk Tuah with Haliey Welch.

She said that she had been tagged in multiple TikTok posts that alleged there were “trafficking tunnels” under the Playboy mansion linking to Diddy’s Los Angeles-area home.

“It’s not true,” she shared, as seen in the clip below. “In 2015, Playboy thought it would be cool to, like, start this quirky little rumor that there were hidden tunnels underneath the mansion that went to some old ‘70s actor’s houses. They had these fake blueprints drawn up and they were doing tweets… It was for April Fool’s. But that was right before everybody kind of went Q-Anon. People latched onto that rumor and people think it’s real.”

Young Buck, who recently accepted a plea deal in a trial resulting in him avoiding jail time, has been at odds with his former collaborator for years. Before his recent issues with Fif, he was kicked out of G-Unit in 2009 for his behavior and later unceremoniously left the group again in 2018 alongside fellow members Kidd Kidd and Lloyd Banks. In the years since, 50 Cent has relentlessly trolled his former bandmate, and he even shared a picture of his mugshot and made fun of the shape of his head when Buck was arrested last year.

Last year, Buck agreed to pay $200,006.90 to 50 Cent to settle their long-running bankruptcy case. 50 Cent alleged that he gave a personal loan of $250,000 to Buck years back, but Buck maintained that it was an advance for records he was scheduled to release under the G-Unit label. Buck’s estate amassed approximately $1.05 million through the liquidation of his assets that include his music catalog, vehicles, jewelry and studio supplies, although $445,000 of that was already gone due to legal and administrative costs.
