Has Jesse James found romance again — with another tattooed woman?

In Las Vegas On Sunday, the motorcycle mogul checked out "BODIES: The Exhibition" at the Luxor Hotel & Casino. His companion: Kat von D, the tattoo artist and star of TLC's L.A. Ink.

The twosome were "holding hands the whole time" during their visit, an eyewitness tells UsMagazine.com — and more.

The observer says that James, 41, and von D, 28, "shared a passionate kiss" while checking out the "circulatory room" of the exhibit. Says the witness: James "stood behind her and was hugging her from behind."

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

Despite this and other reported sightings of the affectionate pair in Vegas and West Hollywood over the weekend, von D's rep tells Us, "They're just friends — that's all."

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

Back in May, Kat defended McGee and other tattooed women to Us. "You can't judge a book by its cover," she told Us at a May 1 event in Beverly Hills.  "I think there has always been a negative stigma surrounding tattoos, especially on women," continued the reality star, who recently split from Motley Crue rocker Nikki Sixx.
