Jon Jones: I Wanna Join TMT ... But Floyd Won't Call Me Back!!

Jon Jones claims there's one small issue stopping him from joining Floyd Mayweather's Money Team ... Floyd won't call him back ... saying the two men haven't spoken since Floyd made the offer.

Floyd told us the UFC superstar was a perfect candidate for Money Team membership when we got him at his daughter's crazy b-day party ... so when we got Jon out we had to ask about the status of his crewship.

Check out the clip -- seems like there's a little miscommunication going on, 'cause Jon says he'd love to join up with Floyd ... but hasn't had contact with him since he was invited to join.

Weird, you'd think he'd want to brand JJ with TMT gear before he gets in the Octagon at UFC 200 on July 9th.
