Kate Hudson was a blushing bride on Saturday night – but there wasn’t a groom in sight.

The actress's 37th birthday festivities continued with her annual “Hot Mess” party, a joint celebration of she, jewelry designer Jennifer Meyer, and author Derek Blasberg’s special days, held at her Pacific Palisades, California, home.

“It was some night,” Hudson wrote of the party, alongside a photo with the birthday stars. “Love you guys #NothingLikeAJointBday #AprilBabies #AnnualHotMessParty #WeddingEdition.”

Hudson and Meyer were dolled up in all white, and both donned tulle wedding veils. Meyer turned 39 on Saturday, and Blasberg turned 34 on Friday. Kate Hudson celebrated her day earlier in the week, on Tuesday.

Other guests came in wedding-themed attire, and Rachel Zoe looked stunning in a black and white striped gown.

Erin Foster shared a fun photo with Hudson’s brother Oliver Hudson from the party, which featured the cowboy hat-clad star posing with his shirt pulled up.

This marriage will never last.
