Elisabetta Canalis

Celebrity trends may come and go, but we are thrilled to see the denim shirt holding steady among Hollywood's hottest. Every celeb has her own way of wearing the trend, and we particularly love how these 17 stars worked the basic fashion staple. Channel your inner fashionista by styling denim on denim like Kate Bosworth, balance a pair of darker bottoms with a denim top like Taylor Swift, or layer a chambray blouse over a floral maxi skirt like Jenna Dewan. As you can see from these looks, a denim shirt is super versatile; it works well with everything. So step inside to see more celebs working the trend, then shop our favorite picks.

This week officially kicked off Summer, and the stars celebrated the season by busting out their bikinis and striking up some romance. Katie Holmes and Suri Cruise enjoyed a day at the beach in Miami, while Jennifer Aniston and Justin Theroux got cozy in NYC. Meanwhile, George Clooney and Elisabetta Canalis called it quits, and the Jolie-Pitts enjoyed some work and play in Malta. Check out all of these memorable moments, and even more, in the gallery!

George Clooney and Elisabetta Canalis have split after getting together in 2009. The duo released the news in a joint statement today. They said, "We are not together anymore. It's very difficult and very personal, and we hope everyone can respect our privacy." The love affair may be over, but we're taking a look back at George and Elisabetta's years-long romance from sweet motorcycle rides to steamiest red-carpet moments. Click through to see the former couple's most memorable moments!

George Clooney brought his boat out onto Lake Como yesterday afternoon. He had his friend Ben Weiss for company, since Elisabetta Canalis had to head into Milan for an appearance on the show Fornelli and Coltelli. George is in her home country of Italy during a break from shooting Gravity in London with Sandra Bullock. There's been time for date nights for Elisabetta and George at their favorite restaurant, Il Gatto Nero, not far from his vacation home. Work separated them again yesterday, so Elisabetta could be on TV. She donned an asymmetrical orange tube dress, which she paired with an apron to do a cooking demo that involved zesting lemons before showing off her skills on the dance floor.

George Clooney and Elisabetta Canalis had dinner yesterday at a romantic restaurant, Il Gatto Nero, in Cernobbio, Italy. It's one of their favorite spots near his Lake Como home, as George and Elisabetta dined there last August too. The couple are in Elisabetta's home country, so that George can work on an ad campaign during a break in shooting Gravity, which he's been filming in London alongside Sandra Bullock. George has even been able to bond with Sandra's son Louis, as the trio was photographed having fun with an iPhone during downtime on set. Elisabetta and George haven't been seen together much over the last few months, but they've apparently just been keeping their romance away from the public eye. In fact, Elisabetta recently spoke about her marriage plans with George, saying that she's not aching to settle down yet but does hope for a wedding someday.

George Clooney had his girlfriend Elisabetta Canalis by his side yesterday when they arrived at Milan's Principe Di Savoia hotel. He's apparently left the London set of Gravity in order to shoot a commercial in Elisabetta's native country. George has been focused on his new project, though Elisabetta hasn't slowed down her interviewing and press work. In a recent issue of the Italian language magazine Chi, Elisabetta said she and George might marry. "I am very happy at the moment — thanks to my man and my fairytale is continuing. We are a couple that never gets bored," she said. "I am a firm believer in marriage, in the future I will be married, but for the time being I am happy as I am. I don't need anything to confirm how happy I am." George is well known as one of Hollywood's biggest bachelors, but he and Elisabetta nonetheless seem to be going strong as they come up on their second anniversary this Summer.

Bar Refaeli had her third night in a row out on the town yesterday when she stepped out to celebrate the opening of Roberto Cavalli's new Cannes boutique. The designer, who recently hosted bikini-clad Elisabetta Canalis on his yacht, gathered famous friends for drinks and dinner on the vessel following a small shindig at the store. Elisabetta was also on hand to toast Roberto, as were Brooke Shields and Rosario Dawson. Bar kept the fun going by hitting an afterparty at the Martinez Hotel, where she met up with her fellow models Irina Shayk and Alessandra Ambrosio. The evening wrapped up with a tweet from Bar that said, "Nothin' better than taking my makeup off, shower, pajamas, bed and book!" She needs the sleep between her whirlwind film festival schedule that has included hitting the red carpet at The Beaver premiere, a bash on Paul Allen's big boat, and attending a Chopard party with Jude Law and Naomi Campbell. Bar's not slowing down in the wake of her split from ex Leonardo DiCaprio, who was spotted with Blake Lively sparking rumors of romance. Today, Bar was back to having fun and she shared a photo of herself lounging on a yacht in a mismatched bikini.

Elisabetta Canalis was back in her bikini to hang out with girlfriends on a yacht docked near Cannes this morning. She's enjoying the social side of the city's film festival, which is taking place not too far from her home base in Italy. Elisabetta is no stranger to jetting around the globe for fun, though. She and George Clooney are well known for their love of shirtless- and two-piece-filled getaways in Cabo, though he's been busy lately focusing more on movie making. He spent time in the US shooting The Ides of March, a project he both directed and acted in, and he's apparently now in the UK working on Gravity. Elisabetta hasn't been spotted by his side in a while; however, they were apparently together in his native Kentucky in February for a dinner date with his parents.
