Future didn't need a diss track to unleash his true feelings about Ciara and Russell Wilson -- he just came right out and said she's controlling ... and he's weak.
The rapper was interviewed by his friend Big Bank Black Thursday night for Beats 1 radio and took some shots at his ex ... starting off by claiming she introduced their son, Future Jr., to Wilson before he gave it his blessing.
Future then blasted the Seahawks QB by declaring Ciara controls him, saying ... "He do exactly what she tell him to do."
Future seems to especially have a problem with Wilson allowing Ciara to talk trash about him on social media. Future says, "He not being a man in that position ... he not tellin' her, 'Chill out with that on the Internet. Don't even talk to him. I'm your husband! You better not even bring Future's name up.'"
It sounds a tad hypocritical, but Future says if he was in Wilson's position, he'd have more control over his girl ... and wouldn't let her publicly slam an ex.
We broke the story ... Ciara wants a mediator in her ongoing custody battle with Future to help hash our their son's travel schedule. She claims Future hasn't been the best dad -- allegedly breaking scheduled visits fairly often -- and tends to hand their kid off instead of spending much time with him.
Ciara didn't just make these claims on social media either ... it's all in legal docs.
