Katie Holmes showed off her dance moves at a star-studded Summer soiree in the Hamptons last night. The evening — which celebrated the east end's Apollo Theater — also brought Ellen DeGeneres; Jamie Foxx; Mary-Kate Olsen, who had her boyfriend, Olivier Sarkozy, by her side; and Pharrell Williams together to party it up in the Summer hot spot on Long Island. Designers Calvin Klein and Donna Karan, as well as former Secretary of State of Colin Powell, were all in attendance for the evening, which included live performances from Pharrell, Jon Bon Jovi, and Lenny Kravitz.
The Hamptons have become a popular destination among celebrities, and last night's bash was not the only star-studded happening in the Summer hot spot this weekend since Gwyneth Paltrow hosted a garden party celebrating her weekly newsletter, Goop, alongside Stella McCartney, in Amagansett, NY, on Friday. Jennifer Lopez, Cameron Diaz, and Sarah Jessica Parker have all gotten in on the action this Summer with relaxing getaways in the Hamptons as well.
