She wins! 50 Cent divulged more details about his supposed confrontation with Beyonce on Monday, June 2, casually mentioning that the true star of the actual run-in at the Cosmopolitan in Las Vegas was none other than Solange. The rapper hosted a Starz Series "Power" event at the Highline Ballroom in NYC, and confirmed the encounter to reporters.

"Yeah, yeah it happened," he said of the altercation. (As the rapper explained in his radio interview, Beyonce was none-too-pleased with 50 that night and approached him while defending her husband Jay Z. "She bugged out at me," 50 recalled. "I looked and Jay starts laughing. He's like, 'Yo, you know what it is.'")

"We were in the Cosmopolitan on New Year's Eve," the rapper continued, "and we all ended up in one room."

Who exactly was "We all?"

"Jennifer Lopez, Rihanna, Kane, Solange…" 50 Cent explained of the star-studded event, which took place in 2011. Other A-list attendees at the party included Gwyneth Paltrow and Chris Martin, Cameron Diaz, John Mayer, and Kanye West.

Though Beyonce clearly was the fiery one at that particular event, 50 explained that the true winner—both past and present—was the diva's younger sister.

"Solange was the biggest one there!" the "In Da Club" rapper joked. "Look, after you whip somebody's ass in the elevator, you're the biggest one!"

Indeed, 50 Cent was intrigued by last month's Met Gala afterparty elevator scuffle, even narrating the footage in multiple Instagram clips. His videos, unfortunately, were promptly deleted.

His new TV series, Power, will premiere Saturday, June 7 at 9PM ET/PT on STARZ.
