Kevin Leesays Jake Paul vs. Nate Diaz ain't happening, but there's another MMA star who is down to book a fight with "The Problem Child" -- "The Motown Phenom" himself tells TMZ Sports he wants to fight JP!
"If Jake Paul is serious about [MMA] and if he really wants to fight. If he wants to have that respect, he wants to have that attention, he wants people to take him seriously, he's going to have to fight a serious fighter," 30-year-old Lee told us in the aftermath of Jake signing with PFL (Professional Fighters League).
"He's going to have somebody for real, for real. I'm the best option for that. I'm in my prime. I've fought the whose-who of MMA. I've fought six different world champions."
After announcing the signing, 25-year-old Jake, 6-0 as a professional boxer, issued a challenge to Diaz -- a boxing match followed by an MMA fight -- against the combat sports superstar from Stockton, CA.
It's not that Kevin doesn't like Jake vs. Nate ... he's actually into the fight.
"Nate Diaz is a good fight. I'll give him that, but there's two problems with the Nate Diaz fight. Nate Diaz ain't going to take that fight, let's be honest. They're going to go back and forth for months and years," Kevin said, explaining Diaz would first need to sign with PFL, which Lee says will not happen.
Kevin says if they make it happen, that's great for them ... but if Jake wants to fight a top-of-the-line MMA fighter in the near future, Lee's the guy.
"If he makes the Nate Diaz fight happen, great but I don't see that happening within the next year or so and if he wants to fight this year then he should fight somebody that's on the roster and already making it happen. Nate Diaz is a good fight, though. I ain't hating."
We asked Lee, who says he's on the verge of signing with PFL, whether he had a message for Paul.
"Let's make it happen. Be a man. Put your money where your mouth is. Step in there. You might lose. You're going to lose. It's going to happen but I'm gonna shake your hand afterward and let's make some money."
"Let's put on for the kids that are watching and want to be the next ones up. Let's show them the right route to take. and let's show them what they can really do if they put they balls to the side and let's make it happen. Let's go ahead. Let's fight. Let's see what you do."
