Kate Hudson Celebrates Her 'Groovy' 40th Birthday with Star-Studded 4/20-Themed Party

No one throws a party like Kate Hudson!

The actress celebrated her 40th birthday in style on Friday night, hosting family and famous friends at her home for a night full of fun, food and even a nod to 4/20.

The festivities had a star-studded guest list that included Leonardo DiCaprio, Johnny Knoxville, Reese Witherspoon, Sara Foster, Erin Foster, Katy Perry, Orlando Bloom and more.

Guests took part in a pizza-making class, before munching on cannabis-infused goodies from Kiva Confections.

Hudson’s mom Goldie Hawn (who attended with longtime love Kurt Russell) seemed to enjoy the large pink birthday cake, as she was seen licking the frosting off of her fingers as seen in an Instagram post from Derek Blasberg.

“After vacillating whether or not to do a birthday party for — hmm — about six months, yesterday morning @katehudson finally relented and let her friends take over her house, install a pizza oven and tequila bar, and celebrate her big 4-0,” Blasberg, 36, wrote.

“It was spontaneous and bohemian and fun and fabulous, just like the birthday girl. And everyone had a finger-licking good time, just like her mom,” he continued.

Stylist Jamie Mizrahi shared a sweet selfie of some of the guests, including Hudson’s brother Oliver, Hawn and Foster. “HAPPY 4-0 KH we ❤️ u,” she wrote.

The birthday girl also shared a social media video of three champagne glasses toasting, writing, “Full moon rising, Good Friday, Passover, my birthday…do you know what that means? Neither do I but it sounds groovy #KivaConfections.”
