Some very single, very available TMZ spies stumbled upon a profile for a person calling himself "d33pthr0at" -- which features a candid picture of the rock star and a description which matches Tommy exactly -- single, Caucasian, drummer, 46, has kids, smokes and drinks regularly, travels a lot ... and is rich as can be.

But Tommy's people swore in a statement, "Tommy Lee has no knowledge of this website or of this posting" -- which means the person who wrote the following unbelievably Tommy-sounding "About Me" description, is a total fraud: "WHAT UP BEAUTIFUL BUNNIES. I'M TOMASS, LOOKING FOR HUNNIES TO PARTY WITH, MOSTLY WEST COAST BUT I TRAVEL THE WORLD SO IF YOU ELSEWHERE, WE COULD STILL CHILL."
