Hayden Christensen is a very lucky man to have the stunning Rachel Bilson for a girlfriend!

Here are five pictures of the happy couple vacationing in Barbados this week.  I have to say, Rachel Bilson has never looked better, and the pair seems to be having a lot of fun swimming, sunbathing and being in love.  Jealous?

‘The Bling Ring’ is based on the real-life group of teenagers based around Calabasas, California, who burglarized the homes of several celebrities including Paris Hilton, Megan Fox, Rachel Bilson, Lindsay Lohan, Orlando Bloom and Ashley Tisdale.

Emma plays Nicki, a girl whose ex-Playboy model mother (played by Leslie Mann) schools her two daughters on the importance of being famous.

Sofia Coppola is directing the project, which began filming in March.

Emma Tweeted from the set of the movie: “Filming Bling Ring is going great. As Israel would say ‘we are slaying this!’. Thanks for the good luck messages.”

Rachel Bilson looks great in a bikini! The 29-year-old actress was spotted in two different bikinis in Barbados over the weekend, where she’s vacationing with boyfriend Hayden Christensen.

The couple – who have had a rocky relationship – seem to be back in love. The couple began dating in 2007 after meeting on the set of ‘Jumper’. They reportedly became engaged later that year, but have been on/off since then. They called off their engagement last August.

A representative for Bilson, who starred in The O.C., told People magazine: ‘Yes, the engagement is off.

Work commitments meant the couple had been living separate lives, with Rachel based in Los Angeles, while Hayden was in Canada.

The distance between them was one of the main reasons for the split, a friend said.

‘It just wasn’t working out,’ the friend told People, adding that Bilson was ‘focusing on her career, spending time with her family and just moving forward.’

But three months later in November 2010, it appeared that the couple couldn’t bear to be apart and reportedly started dating again.

And now they appear to be getting completely back on track. They worked together again two years into their relationship in 2009 on one of 11 short films that made up New York, I Love You.

Bilson previously dated Adam Brody, her co-star on The O.C., for three years. Since leaving the show she has moved into film, and was seen earlier this year in Waiting For Forever opposite Tom Sturridge.

Rachel Bilson is ready to go in a white long-sleeve tee, denim shorts, flat booty shoes, and a casual black Chanel purse! She makes the most of her day and meets with a couple gal pals in Sherman Oaks, Calif., yesterday (March 10). Rachel pays for her parking meters, grabs lunch, a hug, and stays in good company!
