If Janine Lindemulder is to be believed, Jesse James and Kat Von D have been dating a lot longer than people think.

Lindemulder, James' ex wife and mother to their 6-year-old daughter Sunny, tells Life & Style that the 'Monster Garage' star and the famous tattoo artist were together for months before taking their relationship public.

Right after James and Von D announced they were dating in August, Lindemulder remembers, "I got Sunny on the phone and she said, 'Kat's here.' Then she said to me, 'You know, Mom, I haven't known Kat just a couple of weeks. I've known her for months.'"
