James' volatile relationship with Lindemulder was recorded on the Discovery network special "Motorcycle Mania 3," but little is known about his first wife, Karla James, whom he met before he became a popular television personality.

James and Karla have two children, daughter Chandler and son Jesse Jr., and Karla reportedly lives within walking distance of James' oceanfront home near Long Beach, Calif.
James, who claims to be a relative of the famous outlaw Jesse James, has made no secret of his past. According to Fortune magazine, he was a regular visitor to California's juvenile detention centers as a youth. His college football career ended early with a knee injury but he found work as a bodyguard, touring with Madonna, Nirvana and Metallica.
Injured on the job, he returned to his first love -- welding -- and, with his longtime interest in motorcycles, opened his own shop, West Coast Choppers, in Long Beach in 1992.
The company grew into a high-end custom bike shop with customers like Keanu Reeves, Shaquille O'Neal and Kid Rock, and caught the attention of the Discovery Channel, which made James into a star with "Monster Garage" in 2002.
The woman who may be responsible for Sandra Bullock's surprising split from husband Jesse James bears more resemblance to James' second wife, tattooed porn star Janine Lindemulder, than the girl-next-door actress. Close
James married Lindemulder, who is also known for her association with punk band Blink 182, that same year. Their marriage lasted only a year. According to Lindemulder's attorney, James left her when she was seven months pregnant with their daughter Sunny.
James met Bullock in 2003, when she brought her then-10-year-old godson to the set of "Monster Garage" for a tour. Sparks flew, but James decided to approach this relationship differently. "I took my time and got to know her and did it right, and it was a great courtship," he told People magazine in 2006.
Bullock's Long-Awaited Marriage
Bullock, who was once engaged to actor Tate Donovan and involved with Troy Aikman and Matthew McConaughey, put off marriage, which she once called "a death sentence," and focused on her career, until she married James in July 2005 at the age of 40.
"Everyone was surprised when they got married," Malkin said. "But she put a lot of thought into this. "Her romantic life was never messy, there was nothing to indicate she ever made horrible love choices."
Jesse James and Sandra Bullock in happier times
Bullock even put her career on hold while helping to raise James' three children and got involved in his custody battle with Lindemulder over Sunny, whom he successfully fought to keep after Lindemulder went to prison for tax evasion.
"I myself have stopped working like I used to in order to be here with Jesse and the kids because we are on constant high alert," Bullock wrote to the court, "never knowing what condition Janine will be in, and even more concerning, the condition [the girl] will be in."
Now, amid reports of James' infidelity, Bullock's relationship with James and his children appears up in the air. But Malkin thinks Bullock will be fine.
"This is a strong woman," he said. "No matter what happens, she's going to come out strong. This is not someone you push around. As sweet as she is, she's tough."
