Cher, Timberlake attend Hudson birthday

Cher, Justin Timberlake and Demi Moore were among the guests at Kate Hudson's 30th birthday party at Pacific Palisades, California last week.

Hudson's mother Goldie Hawn, 63, and her partner Kurt Russell, 58, also attended the event, which had a lengthy celebrity guestlist.

According to People, Ashton Kutcher, Matthew McConaughey, Tobey Maguire, Jessica Alba, Gwyneth Paltrow, Chris Martin, Gwen Stefani, Adam Sandler and Zach Braff also appeared at the event.

"Kate was elated, dancing all night, having the time of her life," said a source. "She looked amazing in a very sexy little dress and [Christian] Louboutin heels.

"She gave a very touching speech and spoke about how important her family is to her."

Justin Timberlake was the "life of the party", claim sources. "He was dancing, drinking tequila, and he had everyone doing the 'electric slide' on the dance floor," said a witness.
