9. Eva Herzigová and Gregorio Marsiaj
Eva Herzigová definitely didn't show any signs of her 2011 pregnancy at a Cannes party in a tight leather dress. The model showed off her best accessory, beau and baby daddy Gregorio Marsiaj, at the event. Any man who can pull off a tux and sunglasses so well is a keeper.
10. Chris Pine and Dominique Piek
Chris Pine and model Dominique Piek made their debut as a couple on the red carpet at the opening night gala. The brunette tweeted about their big night: "Nothing could have prepared me for the crazy red carpet experience. Thank goodness I made it in one piece up the stairs!"
11. Julianna Margulies and Keith Lieberthal
Julianna Margulies plays an attorney on The Good Wife, and she's married to one in real life. She and Keith Lierberthal have been married since 2007 and have a son together. They escaped parenting duties for a few days to hang out in France.
12. Karolina Kurkova and Archie Drury
Model Karolina Kurkova brought some color to Cannes. She and fiance Archie Drury hung out at the On the Road afterparty, but the hot blonde flew solo at the star-studded amfAR gala in a stunning see-through number later in the week.
13. Eva Longoria and Eduardo Cruz
Eva Longoria walked the red carpet solo at all the big premieres, but she was spotted partying on a yacht with her on-again beau Eduaro Cruz. The sexy pair first started dating in January 2011, but called it quits this March. It would appear that they've patched things up.
14. Boris and Lilly Becker
Former No. 1 pro tennis player Boris Becker isn't a movie star by any stretch, but he does have a hot wife. He and the missus married in 2009, welcomed a son in 2010, and wore clashing shades of white on the red carpet in Cannes in 2012. Then they went yachting.
Looks like Tara Reid's found a new man to buy her nice things and a trip to Cannes. The actress is reportedly dating jeweler Fawaz Gruosi, who's a good 24 years older. They stepped out together at the festival and even kissed for the cameras. Gruosi is known to spend millions on celebrity endorsements and seems to have a proclivity for hot younger women.
This is a long shot, but there's a possibility that Robert Pattinson and Kristen Stewart could step out as a couple at Cannes this year. Why? Well, the final installment of the Twilight franchise, Breaking Dawn: Part 2,
hits theaters in a few months, so their debut would mean some serious
press for the film. Plus, since they're no longer co-stars, it seems
like the perfect time to finally admit they've been dating all along.
They'll both already be in Cannes to support their respective new
flicks, so the timing seems oh-so right. Will it happen? Stay tuned!
Rachel McAdams made her public debut with Midnight in Paris co-star Michael Sheen
at last year's Cannes Film Festival. They'd been linked since the
Toronto Film Festival a few months earlier (insiders said they were
caught smooching there), but the duo made it official in France last
May. Eyes were definitely on the blonde actress, who was wearing what
looked to be an engagement ring on her left hand. However, her rep
assured everyone that the stars were "100 percent not engaged." They're
still plugging along, but have no plans to walk down the aisle just yet.
Leonardo DiCaprio had just dumped girlfriend of nearly five years, Bar Refaeli, when he made his first public appearance with Gossip Girl star Blake Lively
while in Cannes last May. The pair seemed inseparable as they snuggled
aboard a luxury yacht and the cameras snapped away. Unfortunately, it
wasn't long before Lively moved on with Green Lantern co-star Ryan Reynolds. Will those two step out at Cannes this year? 
Ronson
avoided the red carpet together, but they did seem to confirm
speculation about their romantic relationship at Cannes in 2008. They were spotted making out at Diddy's yacht party and it was all caught on camera. About a month later, Lohan roundaboutly confirmed that the gals were dating. They lasted about a year before going their separate ways.
Just weeks after model Petra Nemcova called off her engagement to Jamie Belman, she stepped out at Cannes with former fling Sean Penn.
Nemcova, 32, and Penn, 51, had their first go-around back in 2008, but
it only lasted a couple of weeks. Now, they seem smitten all over again.
The pair has attended many of this year's film events together,
including Penn's high-profile Haiti benefit Friday night. The blonde has
been sure to wear plenty of glitzy gowns while flirting with her man in
front of the cameras. He doesn't seem to mind at all.
Illustrated model Dominique Piek
have been rumored to be dating since last fall, but they had managed to
escape the cameras until choosing to step out together at Cannes
earlier this week. They held hands on the red carpet at the opening
night gala Wednesday and showed the world what a stunning pair they
make. Piek stole the show in a skintight Giorgio Armani gown while Pine
looked dapper in a nondescript tux. The brunette tweeted about their big
night: "Nothing could have prepared me for the crazy red carpet
experience. Thank goodness I made it in one piece up the stairs!" 
This Desperate Housewives star didn't exactly make her big debut with Penelope Cruz's brother Eduardo
at Cannes, but they did make their "we're back together" debut at the
film fest. The pair had been dating since January 2011, but they
reportedly split in March of this year. However, rumors of a reunion
went around weeks later, but those reports weren't confirmed until they
stepped out at a fancy yacht party in France Friday evening. It looks
like things are back to normal, especially since Cruz was spotted in his
favorite black hat and unbuttoned white shirt.
