Sandra Bullock's ex Jesse James is hoping the fourth time is the charm.

Although his past relationships have been splattered all over the tabloids, the 43-year-old "Jesse James: Outlaw Garage" star hasn't given up on love – and said "I do" to wife number four, Alexis DeJoria, over the weekend.

The West Coast Choppers gearhead married the drag racer Sunday in Malibu, California. The wedding took place at the estate of the bride's father, John Paul DeJoria, who is the billionaire businessman behind the Paul Mitchell hair care products line and Patron Spirits Company.

The youngest of James' three children – his daughter Sunny, 9 – was a flower girl in the service along with DeJoria's 10-year-old, Bella. The couple's wedding rings were designed by Neil Lane.

While the custom motorcycle maker has not officially confirmed his new marital status – and his manager has not yet responded to omg!'s inquiry – James dropped a big hint on Instagram and Twitter on Sunday.

Along with a photo of himself walking hand in hand with DeJoria, he posted the quote, "Happiness is only real when shared – Jon Krakauer," and tagged his new bride in the post.

When one of his followers questioned the quote, James replied, "No sorry it's not bulls**t. It's 100% True. Everything before seems so silly compared to how perfect she it. I have never felt so happy and so loved.”

Of course, James has a colorful "before." After failed marriages to first wife, Karla, and porn star Janine Lindemulder (with whom he was engaged in a nasty custody battle over Sunny), James married Bullock in 2005. Their marriage spectacularly imploded in 2010 when numerous women came forward to reveal they'd had secret affairs with James. Soon after he became engaged to tattoo artist Kat Von D, but she called things off amid accusations he had cheated.

James and DeJoria, who drives the Patron Nitro Funny car on the drag race circuit, reside with their combined brood in Austin, Texas, where he recently relaunched West Coast Choppers after a four year hiatus. They became engaged late last year.
