Kate Hudson celebrated turning 30 with a star-studded bash at the weekend. The Bride Wars actress celebrated her landmark birthday with a host of famous faces including Demi Moore and her husband Ashton Kutcher, Justin Timberlake, Tobey Maguire, Matthew McConaughey, Jessica Alba and her husband Cash Warren, Gwen Stefani, Eva Mendes, Gwyneth Paltrow and husband Chris Martin, Adam Sandler, Zach Braff and Cher. A source said, “Kate was elated, dancing all night, having the time of her life and she looked amazing in a very sexy little dress. She gave a very touching speech and spoke about how important her family is to her.” The party was held at the home Kate’s mother Goldie Hawn shares with her partner Kurt Russell in Pacific Palisades, California. While Goldie and Cher got into the spirit of the evening by taking to the dance floor, it was Justin who really got everyone in the mood. The party went on until the early hours of the morning, with reports claiming police were eventually called in response to a noise complaint.
