Congratulations are in order for Jackson Rathbone and Sheila Hafsadi. The 28-year-old actor well known for his role as Jasper Hale in "Twilight Saga" movie series tied the knot with his girlfriend on Sunday, September 29.

"It was a small wedding," an insider tells Us Weekly. "Just close friends and family only." The low-key nuptials took place in Malibu, California. According to PEOPLE, around 150 guests were in attendance to witness their union.

Rathbone met Hafsadi, a burlesque dancer, in 2011 during a tour stop in Fort Lauderdale, Fla. with his band 100 Monkeys. "It was one of those things," he recalled. "I always said I believed in love at first sight, but I never really had that feeling before."

The couple welcomed their first child, a baby boy, on July 5, 2012. "I've been wanting a kid for a long time," he once said of his desire to have a big family. "I'll have more - probably two or three."

Rathbone, whose real name is Monroe Jackson Rathbone V, passed down the family name to his first son. "Thank you ALL for the love & support! Sheila & I couldn't be happier to have such a beautiful, healthy baby boy, Monroe Jackson Rathbone VI," he tweeted back then.

Rathbone's co-star Nikki Reed, who plays his vampire sister Rosalie Hale in the movie adaptations of Stephenie Meyer's novels, becomes the godmother of the baby.
