The two rappers signed to Floyd Mayweather's TMT music group are getting special mentoring sessions from some of the biggest stars in music ... including Future, Bieber and more, TMZ Sports has learned.
Floyd launched his rap label last year -- signing Lil Jamez and Jay Bling. He's been showcasing them around the country ever since -- and this weekend, he hit the stage with the guys at Hard Rock Live in Vegas (video above).
“Floyd is a music head. He gets us in the studio and flies us from city to city," Jay Bling tells us.
