Jake Paul's admittedly nervous for his upcoming tilt with Gervonta Davis, but he tells TMZ Sports he's got a bit of a secret weapon in his corner to help him make sure he's ready -- Shakur Stevenson!
The YouTuber-turned-superstar-fighter revealed to us on Wednesday that Stevenson -- who's had his share of beef with Davis over the years -- is slated to meet with him in just a few days to give him an assist in the ring.
Paul said the two will spar -- and he's hoping it'll get him as prepared as possible for Tank.
