Kate Hudson celebrated her 30th birthday with a crowd of A-list celebrity friends.
The Bride Wars star partied in Pacific Palisades, California, at the weekend along with her mother Goldie Hawn and Goldie's partner Kurt Russell, Demi Moore, Ashton Kutcher, Justin Timberlake, Matthew McConaughey, Tobey Maguire, Jessica Alba, Cash Warren, Gwyneth Paltrow and husband Chris Martin, Gwen Stefani, Eva Mendes, Adam Sandler, Zach Braff and Cher.
A source told People magazine: "Kate was elated, dancing all night, having the time of her life - and she looked amazing in a very sexy little dress and Christian Louboutin heels."
The source added: "She gave a very touching speech and spoke about how important her family is to her."
Justin Timberlake may have been out without girlfriend Jessica Biel but according to the insider: "He was the life of the party. He was dancing, drinking tequila, and he had everyone doing the 'electric slide' on the dance floor."
Kate and her mum Goldie were spotted being twirled around the dancefloor by another enthusiastic partygoer.
The party spy said: "Eva Mendes kept a low profile, hanging out mostly with Zach Braff and Cash Warren in the beginning of night. And Adam Sandler came by very briefly to say happy birthday and grab a cupcake, while Cher spent the whole night dancing, of course!"
