A rapper with former ties to Big U is happy the Rollin’ 60s Neighborhood Crips leader has been locked up on murder and conspiracy charges … and wants him put UNDER the jail … she’s claiming to be one of his victims!!!

TMZ Hip Hop recently ran into SKG, a former Death Row artist — whose name stands for “Suge Knight Girl” — out this week and she’s packing a lot of opinions regarding the Big U RICO charges.

SKG tells us Big U was a literal monster to her and the Crenshaw community for years, by allegedly using brute force to extort local businesses.

She also claims Big U beat her in the presence of Nipsey Hussle while she was pregnant!!!

She’s been telling the story for years … Nipsey and his late friend Stephen Jiles “Fatts” Donelson allegedly set her up to be ambushed and beaten by Big U after he was embarrassed by the way he was presented during a meeting with L.A. radio station KDAY.

SKG says she has no sympathy for Big U, but her heart yearns for the family of Rayshawn Williams, the 21-year-old aspiring rapper who federal agents allege Big U murdered in Las Vegas back in 2021.

SKG spoke to Williamson’s family and even got backed up by Wack 100 — another one of Big U’s archenemies — but tells us she feels safer since he’s been arrested.

And despite her rocky past with the late Nipsey, SKG wants everyone to be on the lookout for Big U to be implicated in the rap legend’s murder.

Big U turned himself in on Tuesday while denying all the internet gossip allegations against his character.
