Rachel Bilson is pregnant! And she was pregnant enough to sport a baby bump during a little vacation in Barbados with the to-be father, Hayden Christensen. Rachel Bilson and Hayden Christensen have been through some rough patches over the years, but looks like they are ready for some serious commitment, with the baby coming into the world in less than nine months time. Does this mean that wedding bells are on the horizon for these two?

The pair was engaged previously in 2008, but they broke it off in mid-2010 to "take a break". Fast forward four years and here's baby-faced Rachel Bilson about to become a mother!

"He's so incredibly supportive and considerate," Rachel said of Hayden. "It's so basic - that should be there. Because these things are so much more important when you're older."

This sounds like these lovebirds are ready to start planning their wedding! The 33-year-old 'Star Wars' actor and the 'O.C.' actress met on the set of 2007's 'Jumper' and have been an off-again-on-again couple. But with this baby in the pipelines, starting a family looks like a priority for these two.

"I definitely have family on the brain," Rachel Bilson confessed to Cosmopolitan last year. "Having kids is something I want to see in my future-I hope."

The 'Hart of Dixie' actress loves white dresses too much to even think about skipping the wedding. As the maid of honor at the 'O.C.' creator, Josh Schwartz's wedding, she sported an off-white dress in Santa Barbara. At the Art Elysium 10th Annual Anniversary Gala, she wore a white silk Dior dress with a gorgeous train. Maybe Hayden Christensen should be paying attention to her red carpet style for future reference! Actually he should concentrate his efforts on getting a ring first. Let's hope he won't reuse the one from the first time around.
