Kate Hudson took inspiration from high school for her 30th birthday. She threw a mega house party at mama Goldie Hawn's house. Heck, the police even showed up at 1:30 a.m. following up on a noise complaint. "Justin Timberlake was the life of the party. He was dancing, drinking tequila, and he had everyone doing the 'electric slide' on the dance floor," a source said. "[Kate] gave a very touching speech and spoke about how important her family is to her." Awww. [Ace Showbiz]
