Jesse James and Kat Von D: Kissing Passionately

Jesse James and Kat Von D are totally just friends. As in friends with benefits. Well, unless he kisses all his friends passionately, which we suppose is possible.

In Las Vegas Sunday, the motorcycle mogul checked out "BODIES: The Exhibition" at the Luxor Hotel & Casino with his tattoo artist / L.A. Ink star companion.

The twosome were "holding hands the whole time" during their visit, an eyewitness says, but that wasn't all. We're talking straight up mauling going on here.

According to an observer, Jesse James and Kat Von D "shared a passionate kiss" in the "circulatory room" of the exhibit. Guess we can't say "get a room" ...

Says the witness: James "stood behind her and was hugging her from behind." Ooh, better watch out, Kat. That's how it all starts, right Michelle McGee?

Jesse James. Kat Von D. It was bound to happen.

Kat Von D (real name Katherine von Drachenberg) evidently had a great time. Before exiting, she signed the guest book, writing, "Completely mind-blowing!"

Imagine what she had to say about the Vanilla Gorilla after!

Despite this and other reported sightings of the affectionate pair in Vegas and West Hollywood, Von D's rep insists "They're just friends - that's all."

James' five-year marriage to Sandra Bullock famously imploded after his affair withMichelle "Bombshell" McGee, a tattooed stripper, came to light.

Back in May, Kat came out and defended McGee and other tattooed women, saying "You can't judge a book by its cover" and positing that "there has always been a negative stigma surrounding tattoos, especially on women."

Mistresses who help guys cheat on popular movie stars, then cash in on the story for their 15 minutes tend to carry a certain stigma too, of course.
