The actress celebrated her 35th birthday at No Name in Los Angeles on Saturday, where she looked stunning in a sexy, sequined jumpsuit.
The sparkling one-piece featured a low-plunging neckline that showed off her décolletage and stretched to her waistline. She completed the look with a velvet blazer and black platform pumps.
The mother-of-two partied the night away from a bunch of her famous friends, including fiance Matt Bellamy, Reese Witherspoon, Nicole Richie, Jessica Capshaw and Demi Moore. Jewelry designer Jen Meyer, who's married to Tobey Maguire, was also celebrating her big day.
Fashion journalist Derek Blasberg shared two photos on Instagram of the fun festivities, one of Meyer and Hudson blowing out their birthday brownies and another of a group of ladies making silly faces.
Witherspoon posed with the group of blondes in the photo that was captioned, "Reese, Jessica, Kelly, Jen and Emily: Blondes. Having more fun. Happy birthday!"
"Everyone was dancing and having the best time. Kate and Matthew seemed totally in love. They held hands and kissed throughout the night," a source told E! News. "It was a really fun night, everybody had a blast."
It looked like an amazing night!
