They're on a boat!

Rachel Bilson and Hayden Christensen attended a launch party at Harle Yacht in Cannes for Hayden's new production company Glacier Films. The usually camera-shy couple has been dating on and off since 2007.

The Hart of Dixie star stepped out in style to support her beau, who announced the new production company's 11-picture slate scheduled to shoot over the next three years. Production will begin with American Heist, which Hayden will star in.

Rachel, who donned an adorable Dolce & Gabbana dress with black stockings, will star in the comedy The To Do List with Aubrey Plaza, Christopher Mintz-Plasse, Alia Shawkat, and Andy Samberg. The film hits theaters on August 16.

Despite her busy work schedule, the actress told Cosmopolitan that she's anxious to start a family.

"I definitely have family on the brain," she said. "Having kids is something I want to see in my future -- I hope."

She also said she strives to be the best girlfriend possible.

"I'm a really good girlfriend -- I always put all that first in my life," she told the mag. "I'm definitely the person who would make him his favorite dinner to come home to. ... I love to cook, so we make dinner at home a lot and watch movies."

That explains why we rarely see them out and about.

Isn't she just the cutest?!

Rachel Bilson appears on the latest cover of Cosmopolitan magazine, and the O.C. hottie was unusually candid in her interview, even speaking about her relationship longtime boyfriend Hayden Christensen!

"I'm a really good girlfriend - I always put all that first in my life. I'm definitely the person who would make him his favorite dinner to come home to. I love to cook, so we make dinner at home a lot and watch movies," she tells the mag.

So will the couple, who have been dating six years and were briefly engaged before calling it off in 2010, add children into the mix anytime soon?

"I definitely have family on the brain. Having kids is something I want to see in my future - I hope," she adds.

She's looks so young we forget she's old enough to think about settling down!

All of the babes were out last night!

Rachel Bilson and Rosie Huntington-Whiteley were just a few of the celebs that came out for the BlackBerry Z10 Smartphone launch at Cecconi's in West Hollywood last night, and the ladies didn't disappoint in their sexy ensembles!

The brunette actress looked demure in a strapless black cocktail dress, while the Victoria's Secret stunner kept it a little more casual in black pants and a peach blouse.

Other celebs that attended the bash include Tim Allen, Josh Duhammel, Chloe Moretz, Christina Ricci and Stephanie Pratt, among others.

Let's hope they all got free phones in their goodie bags!

Rachel Bilson and Hayden Christensen were snapped leaving a friends house in Los Angeles, and we still don't see an engagement ring on her hand, but the on again/off again couple have been on again for quite some time!

The two started dating in 2007, and after getting engaged in 2008, they called things off in early 2010, only to get back together later that year, but it seems like they've had at least one more breakup in there over the last two years, right?

Bilson recently told USA Today of their relationship, "It's not a secret. I just don't talk about it." I mean, it's not really any of our business, but at this point you have wonder if they'll EVER get married!

What a relaxing Sunday!

Rachel Bilson arrived with treats in hand to her mom's house in Toluca Lake yesterday, and the Hart of Dixie actress makes wet hair and a simple tank top look like perfection!

The former OC stunner seems really family oriented! We always catch her out with her sister Hattie, and it's refreshing to see her being such a good role model for her much younger sibling!

Although her on-again boyfriend Hayden Christensen didn't come along for family day, the pair certainly seem very much back ON! The cute couple were recently spotted shopping for home goods, so all signs point to them shacking up!

We wonder if her family approves of Mr. Christensen?

Does Rachel Bilson own anything that isn't designer?!

The Hart of Dixie actress visited a friend's house in LA today, and of course she looked adorable in booties, a simple black tank, and an orange skirt. Although the 30-year-old looks relatively dressed down, guaranteed that outfit still costs a fortune! Just check out that Chanel bag!

The brunette beauty and her on-again beau Hayden Christensen were recently spotted shopping for home goods, so it sounds like the couple might be shacking up once more!

We're officially on ring watch and waiting for the news that the engagement is back on!

Did Miss Bilson and her boyfriend Hayden Christensen have a baby when nobody was looking?! Just kidding!

Rachel Bilson and a female friend stepped out for a stroll around Los Feliz on Monday, and the Hart of Dixie star got some hands-on mommy experience as she toted her pal's little bundle of joy. Aww how cute!

The 30-year-old former OC actress and her beau have been on and off for years, but with all the recent spottings of them together, we have to wonder... is the adorable duo prepping for parenthood?

We hope so! Talk about the world's most genetically blessed baby!

Are these two ever gonna get hitched?!

The infamously on-again-off-again couple, Rachel Bilson and Hayden Christensen, grabbed breakfast together Friday but maybe there was something wrong with the eggs??

I mean yes, there are photographers around but is that any reason not to hold your boyfriend's hand? Any reason not to cuddle up with your girl? Any reason not to smile?

Note to Hayden and Rachel: The couple that smiles together, stays together.
