Celebrity moms and their families enjoy sunny day at Best Buddies Mother's Day Brunch

Hollywood kicked off Mother's Day weekend with a star-studded philanthropy event -- and we hardly know which mom to look at first! The Best Buddies Mother's Day Brunch, held Saturday in Malibu, attracted a number of stars and their families, all of whom enjoyed the sunny weather for a good cause.

Cindy Crawford, 51, was joined by her mother, Jennifer, and 15-year-old daughter, Kaia. Ever the fashion maven, Cindy stunned in a red off-the-shoulder calf-length dress with fluted sleeves. Kaia complemented her mother's look in a white wrap dress with red dots -- and showed off the gorgeous legs she clearly inherited! Cindy, global ambassador for Best Buddies, paired her bold dress with David Yurman accessories -- we especially love the hoop earrings! Kaia took a cue from her mom, also sporting hoops from the designer, hers from the Cable Classics collection.

Meanwhile, Vanessa Hudgens was flanked by mom Gina and sister Stella. Vanessa, 28, and 21-year-old Stella, who took on Coachella together in April, both wore white crop tops under cozy cardigans. Hudgens donned a numbed of Yurman pieces, adding silver charms (including a covet-worthy sand dollar piece) to her necklace. The affair benefited Best Buddies, which fosters friendships for intellectually and developmentally disabled people.
