Jesse James: Kat Von D is 'my other half'

Jesse James has clearly moved on from his split with ex-wife Sandra Bullock — and he's not afraid to flaunt it.

The 41-year-old "Monster Garage" star, who resurfaced on Twitter January 6, used the social networking site to express his love for current girlfriend Kat Von D.

"I have never felt so loved!" he wrote January 9. "I'm the luckiest MoFo in the world!"

Three days later, James told the tattoo artist that "48 hours away from you feels like a year...you will never be anything but beautiful to me."

Von D's sappy response? "It feels like eternity to me. What are we gonna do? I'm not a stage-five-clinger, but I need you around me, babe."
