Flau’jae Johnson ain’t just getting LSU wins with her skills on the court … Mikaylah Williams tells TMZ Sports her music’s helping fuel the Tigers’ postseason run too!

Kim Mulkey‘s sophomore guard sat down with us on Monday while working a ceremonial shift at a Raising Cane’s in Baton Rouge … and she made it clear, Flau’jae’s tunes are a big part of LSU’s success this season.

She told us the Tigers bump Johnson’s music in the locker room regularly — and get this, she says it’s played so often, they know all the lyrics!!

Johnson, of course, has been rapping for years — and has flashed so much talent, Lil Wayne actually collaborated with her on “Came Out A Beast.” It seems her beats have some good luck mixed in them as well … because LSU is 28-5 this season, and is considered one of the biggest favorites to win the 2024-25 natty.

The Tigers will have to wait a bit longer to find out who they’ll play in the upcoming NCAA tournament — but while the delay might cause a bit of anxiety, it’s sure appreciated … as it’ll give Johnson some more time to rest an injured shin that’s kept her out of recent LSU games.
