Mom-to-be Kate Hudson was celebrated at a baby shower in Malibu on Sunday.

Among the 80 invited guests at the afternoon bash – which took place at a private home – were Hudson's stylist Rachel Zoe and her friends Courteney Cox, Jessica Capshaw and Jennifer Meyer Maguire.

Since Hudson – who is due in July – doesn't know the sex of her child, she "was gifted with gender neutral baby items" at the shower, a guest tells PEOPLE.

"She looked amazing and kept giggling while mingling with friends, nibbling on food and playing games. She seemed to have the best time."

The night prior to the shower, Hudson, 32, and her fiancé, Muse frontman Matt Bellamy, stepped out together to support the Chanel hosted benefit in Malibu for the Natural Resources Defense Council’s Ocean Initiative.

"Kate was just glowing and looked amazing. She and Matt stayed close all night and they seemed very happy together," according to an onlooker.
