Born on November 6, 1972, in Berkeley, California, Rebecca Romijn pursued a successful international modeling career before focusing on acting. She starred as shape-shifter Mystique in the hit X-Men film franchise, with her television work including roles in Just Shoot Me, Ugly Betty, Eastwick and King & Maxwell. Previously married to actor/musician John Stamos, she wed actor Jerry O'Connell in 2007.
Romijn attended the University of California at Santa Cruz in 1990–91, where she lived in dorm 1 at Stevenson College. She studied music and participated in the dorm talent show, singing a musical comedy routine with a high school friend who joined her at UCSC. During the summer following her freshman year, Rebecca began her career modeling and did not return for her sophomore year.
She married actor John Stamos on September 19, 1998. During her marriage, she used the name Rebecca Romijn-Stamos in both her personal and professional life. The couple announced their separation on April 12, 2004, and divorced on March 1, 2005. She has since returned to using her maiden name. It was revealed in an August 1, 2013 interview on Conan that Rebecca had never legally changed her name back from Romijn-Stamos, even though she has been divorced for nine years and re-married for six.
The show's host Conan O'Brien stated that a staffer had noticed "Romijn-Stamos" on her driver's license and she said that she is too lazy to go to the DMV.
Romijn was asked by Elle magazine in April 2002 whether making Femme Fatale had given her any new ideas about her sexuality. She said, "You know, in my early twenties I wondered if I was interested in women and so I kind of, well ... did my homework. And it turns out I'm pretty straight."
On September 19, 2005, Romijn announced her engagement to actor Jerry O'Connell. They were married on their ranch in Southern California on July 14, 2007. On July 28, 2008, it was announced that Romijn was pregnant. Romijn and O'Connell welcomed twin daughters Dolly Rebecca Rose and Charlie Tamara Tulip on December 28, 2008. Dolly is for singer Dolly Parton's first name and Charlie is for O'Connell's brother.
