Sources close to the deal tell us JWoww -- real name Jenni Farley -- just signed a one-night deal to appear on Spike TV's "TNA impact!" on Thursday.
We're told JWoww doesn't have a match scheduled ... but she'll "probably be mixing it up" with a couple of Jersey Shore-alike wrestlers named Robbie E. and Cookie.
But JWoww ain't doin' the wrestling thing for free -- we're told she's pulling in a cool $15 grand for the night ... and the two sides are working out a deal to get her to come back to the show.
... and to think, Snooki didn't get a dime when she got hit on television.
