Sigh, they grow up so fast! Julia Roberts and her husband, Danny Moder, took their adorable kids to an event this past weekend, and they're so big!

The Pretty Woman star and her hubby of 13 years brought their twins Finn and Hazel, 10, and youngest son Henry, 8, to support champion surfer Kelly Slater as he launched his new menswear brand, Outerknown, at Harry Gesner's beach house in Malibu, Calif., on Saturday, Aug. 29.

Roberts, 47, who looked beautiful in black shorts and a matching top, flanked her kids with her husband from behind.

Women's Wear Daily shared some inside details from the kid-friendly event on Monday, and reported that one of the boys "inexplicably hugged Slater’s right foot when they bid adieu to Slater and his teenaged daughter, Taylor."

In an interview with You magazine last fall, the Oscar winner shared updates about how her personal life has transformed recently. "It's about non-grasping, non-hoarding, cleaning out your closet, dusting out your mind and letting go of the things that weigh you down mentally and emotionally," she told the UK publication. "There's a lightness to my life now — an airy quality of not taking things too seriously. That's happiness."

Meanwhile, the beloved actress is focusing on her next big on-screen endeavor, Mother's Day, in which she will star alongside fellow A-listers Jennifer Aniston and Kate Hudson.
