Jennifer Aniston and Justin Theroux continued their romantic vacation yesterday, stopping to grab a cup of coffee on the island of Kauai. The pair are doing their best to fit in with tourists and have been spotted visiting local fruit stands, shopping, and hanging with friends. Jen and Justin even dropped by Christine Taylor's 40th birthday celebration Monday night. Justin's the next one to mark the major milestone in his life when he turns the big 4-0 Aug. 10. Jen and Justin have a few more weeks to enjoy their vacation before work draws them back to the mainland. Their upcoming project Wanderlust is scheduled for an Oct. 7 release, though there's a possibility they could return to LA this weekend for the Teen Choice Awards, where Jen's nominated in two categories for her role in Just Go With It.

Prince Albert escorted his beautiful new bride, Princess Charlene of Monaco, to tonight's 63rd annual Red Cross Ball in their home of Monte Carlo. The princess stepped out in a jewel-toned Akris gown, which was a stark contrast to the classic white Armani dress she wore just last month during their lavish royal wedding. Charlene kept her hair pulled back and makeup simple to complement the stunning custom-made Van Cleef & Arpels piece she wore around her neck. The necklace was given to the princess as a gift from her husband and can also be worn as a tiara. It was reportedly designed to evoke memories of the ocean and is composed of 88 round diamonds, weighing in at over 44 total carats, with 10 pear-shaped diamonds and 359 sapphires!

Ben Affleck supported his three girls and his hometown boys, the Boston Red Sox, while out to breakfast in LA on Friday. Seraphina got playful in her dad's arms as they stepped out after the family meal while Jennifer Garner was on stuffed animal duty. The Garner-Affleck foursome reunited this week when Ben returned from his trip overseas to prepare for his next project Argo. Ben is both directing and starring in the film, which calls for his headline-making longer hair. Ben Affleck kicked off the week in Istanbul, where he met with city officials to talk about shooting his movie there. Jennifer, meanwhile, has been holding down the fort home in California with their tiny karate kid Violet and cutie Seraphina.

Jessica Simpson stepped out of a studio in LA yesterday in a leg-baring sequined gold minidress. Her fiancé, Eric Johnson, met up with Jess later in the evening at the Sunset Tower, though there was no sign of his parents who joined the engaged couple for cocktails over the weekend. Taping has already begun on Jessica's upcoming NBC fashion reality contest, Fashion Star, and according to sources Jess and her fellow judge, Nicole Richie, are getting along great. In addition to filming her show, Jessica's still looking for the perfect wedding dress and launching a new fragrance, I Fancy You. If that wasn't enough to keep her busy, she's also prepping for the Fall release of her latest shoe, clothing, denim, and signature bag collection.

Miranda had her adorable son Flynn on her hip and her red Prada bag on her arm yesterday in Sydney. The model mom has been hanging out with Flynn and her husband Orlando Bloom in her native country for the last week, and while she's had Flynn by her side for much of the trip, she's also been fitting in some work. Miranda sported a sexy swimsuit in David Jones's fashion show on Tuesday, topped off a Summer dress with a fascinator for a shoot last weekend, and stopped for a photocall at the David Jones department store shortly after landing down under. Miranda and her family will likely enjoy some time off during their stay, since she told us back in May that they plan to make the trip a bit of a vacation and a chance to visit with her family.
