O'Connell met actress Romijn in 2004 and they began dating in the same year. They got engaged in September 2005 and married on 14th July 2007 in their backyard at their home in Calabasas, California. The couple exchanged their vows in front of 100 family and friends who believe they had been invited to a BBQ. (IMDB)
Only weeks after they reportedly started trying to get pregnant with their first child, it was confirmed that Romijn was going to have twin girls. When asked about having children, O'Connell said "I am excited I am having girls. I know guys are supposed to say, 'I want a boy. I want to play baseball,' but I think I'm going to be good raising girls...I can't wait. They're going to be tough chicks. They're only having sex when I'm dead. If they don't date boys at all and just want them to be infatuated with their father, that's what I'm really going for." (Wikipedia)
The girls were born on 28th December 2008, named Dolly Rebecca Rose and Charlie Tamara Tulip; Dolly after the singer Dolly Parton (Romijn is a huge fan) and Charlie after O'Connell's brother.
When O'Connell was asked about his wife, he said; 'What I really love about Rebecca is that she's a character...she's the most entertaining person I've ever met.' (IMDB)
Happy Wedding Anniversary Rebecca and Jerry!
