What better way to spend a lazy summer Sunday than with good food and tons of sparkling jewels? That’s just what Nicky Hilton, Jamie-Lynn Sigler, Kourtney and Khloe Kardashian, Christina Milian and more did this past weekend. The star-studded group partied Malibu-style at the Lia Sophia clambake with fried clams, lobster, truffled fries and flavored cocktails. Though the fashionable bunch arrived sans jewels to celebrate the launch of Lia Sophia’s West End III collection, they quickly became well-adorned once they stopped by the jewelry bar. Lia Sophia, a favorite among Hollywood stars like Paris Hilton, Lindsay Lohan, Sienna Miller, Katherine Heigl and more, provided a preview of its new pieces for the line’s famous fans. Nicky picked up some $8,000 worth of jewels. Khloe and Kourtney, who wear the jewelry constantly on Keeping Up With the Kardashians, wasted no time and went straight to the bling before hitting the food. Lia Sophia’s new West End III collection includes gold bangles with black onyx and white finishes, long gold necklaces, colorful jeweled cuffs and more — view it by clicking here. — Reporting by Alexis Chiu
