Andre Berto says he wants to cross over from boxing to the UFC ... and he's 100% serious about it.
"Tell Dana (White) to call me. I'll go to the UFC. I wanna be the first fighter ever to be a world champion in boxing and then go get a world title."
Berto says his whole family has been involved in the MMA world for years ... so it's not as much of a stretch as you'd think.
