Hooray for surprise shindigs!!!
You know we love any excuse for a celebration, so we were especially pleased to hear Muse frontman Matt Bellamy threw his gloriously gifted star of fiancée an epic birthday party!!
Other a-list attendees included funnyman Judd Apatow and beautiful blondes Cameron Diaz and Leslie Mann!!
Apparently the partAAy was pure perfection!!
"Kate loves to dance and she was just really happy talking to everyone. She looked beautiful and beaming in a tight metallic dress."
Aww! We're sure Kate could wear Saran Wrap to her party and she'd still be the belle of her ball!
The Almost Famous star's actual birthday was on April 19th — she celebrated more modestly that evening at a Muse concert!
