Former WWE Superstar and two-time RAW Tag Team Champion Matt Riddle is raking in serious cash outside the ring -- thanks to a side hustle that's turning plenty of heads.
Riddle joined the latest episode of TMZ’s "Inside The Ring" and revealed his OnlyFans account is doing "a lot" for his bank account, crediting much of the success to gay men who watch wrestling and find him "extremely attractive."

He says he keeps it pretty tame -- nothing "too crazy" -- usually just rocking a Speedo and doing workouts on camera .
