WWE Star Hornswoggle -- Follows Through on His Muppet Tattoo Promise

Did you think WWE star Hornswoggle was kidding when he said he was adding three more Muppet tattoos to his body ... in honor of them hosting "Monday Night Raw" next week? Think again.

TMZ got a few pics of the new ink -- Fozzie, Statler, Waldorf and Gonzo -- joining his previous Miss Pigg, Kermit and Beaker tats.
