Jesse James and Kat Von D: Already Fizzling Out?

Is there trouble in paradise for Hollywood's tattooed twosome?
Last we heard, Jesse James and Kat Von D were going so strong, he was going to move back to California to be with her. But there's another side to that coin.
A source says Von D isn't happy about James' move to Austin, Texas, and she's rapidly losing patience with their "weekend fly-back-and-forth relationship."

DEEP-SIXXED: Is Jesse's absence driving Kat back to her ex?

The irony, of course, is that James moved to Texas ostensibly so that his kids could remain close to their former stepmom, Sandra Bullock. Now it's backfired.
In the last couple of weeks, Kat Von D has been spotted getting close to other guys, including her ex-boyfriend Nikki Sixx during a recent Slash concert in L.A.
"They were on the balcony chatting and ended up disappearing together," a source says of the former lovers. "They were acting pretty cozy and chummy."
This week, Von D was "smiling and flirting over an intimate dinner" at a restaurant in Hollywood with another rumored former love interest, Bam Margera.
"They were being very sweet to each other," an onlooker says. "They didn't hang around long, and after a quick cigarette break, made a dash for the exit."
A source says Von D and Margera, who is married, "are not more than friends." Still, they both attended Wednesday night's Jackass 3-D premiere in L.A.
That same night, Von D again spent time with her ex, Sixx.
Better hop the next flight back to Cali, Jesse. One-way.
