Jesse James and Kat Von D are not following in the footsteps of Hugh Hefner and Crystal Harris.
The couple went on the defensive Thursday night after a tabloid claimed that they'd broken off their engagement.
TLC star and tattoo artist Von D (real name: Katherine von Drachenberg) laughed when a fan commented via Twitter about the "silly" canceled wedding story. "Ha!" the 28-year-old wrote. "Silly is correct!"
Motorcycle mogul James, 41, was a bit angrier -- slamming "piece of s*** tabloids" on his microblogging account. "Lick my b****," he sniped.
Pals for years, James and Von D stepped out as a couple last August, just a few months after the Monster Garage star's highly-publicized divorce from Sandra Bullock was finalized. (James cheated on wife of 6 years Bullock, 46, with tattooed model Michelle "Bombshell" McGee.)
