Matthew Bellamy surprised Kate Hudson with huge birthday party. Kate Hudson was turning 34, and the night after her birthday, Saturday the 20th, Matthew surprised Kate in New York City at a friend's apartment.

Bellamy organized the bash, and "Kate was totally surprised," according to reports. Kate Hudson, the "Reluctant Fundamentalist" star, showed up to the West Village apartment and found that her fiancée Bellamy had coordinated high-profile guests including Cameron Diaz, Judd Apatow, and Leslie Mann to surprise Kate.  The apartment was in the West Village and reports say "Kate was totally surprised,"

"The party started outside, but it was freezing so people moved inside and danced," a source said. It might ahe been a more active night than she anticipated-the night before her birthday, she told Us Weekly "I just want to hang with my family." She got to spend her actual birthday doing so, in a sense, if in a loud public place-she watched Bellamy's band Muse perform at the IZOD Center in East Rutherford, New Jersey. "They're very supportive of each other's careers," a source close to the couple insaid. "They're so happy together."

And on Saturday, Kate loved the surprise birthday party-- "Kate loves to dance and she was just really happy talking to everyone," an insider revealed. "She looked beautiful and beaming in a tight metallic dress."

Bellamy and Hudson have a child together, Bingham, who is 21 months old. Hudson also has a son, Ryan, who is 9. The two have been engaged since 2011.
