She’s a new WW ambassador, the cofounder of Fabletics, an actress and a mom-of-three. But according to her pal Sara Foster, Kate Hudson‘s greatest role is being a mother to her sons, Ryder Russell, 15, Bingham Bellamy, 7, and daughter Rani Rose Fujikawa, 3 months.

“Kate is the most hands-on mom and I don’t know how she does it all,” Sara, 37, gushed to People while attending the WSJ Magazine Talents and Legends Dinner on Monday, January 28 in Beverly Hills. “She really does it all. Whoever says women can’t do it all, she does it all.”

Sara’s famous younger sister thinks Kate’s an awesome mama, too! Earlier this week, Erin Foster shared a sweet clip on her Instagram Story of Kate proving she’s a supermom as she breastfed baby Rani while doing leg lifts, squats and static lunges during an intense at-home workout.

“Motherhood doesn’t slow us down,” Erin, 36, captioned a quick video of Kate holding Rani. The star also later included another clip of Kate sitting on a yoga mat on the floor while feeding her baby girl.

In case you didn’t know, Sara and Erin are the step-sisters of Kate’s boyfriend, Danny Fujikawa. And since the fashionable Foster siblings are like aunts to Kate and Danny’s little daughter, Rani, Sara also recently dished on the infant’s “very chic” wardrobe. Apparently, Rani’s closet “has every outfit and turban that you can imagine,” Sara revealed, adding that Rani is “a very chic baby.”

“Kate puts turbans on her and I’m so jealous because I didn’t know about these turbans when I had daughters,” she continued. “Little girls have no hair usually, so these turbans, they’re so cute! I know if I have a third [daughter], I’ll take them all.”

Was Sara hinting that she and her husband, Tommy Haas, might be ready to expand her family? “Who knows. Never say never. Things happen when you’re not paying attention,” the Barely Famous star — who’s a mom to daughters Josephine Lena, 3, and Valentina Evelyn, 8 — said.

Kate also recently gushed that she wants to have more babies with Danny. “At one point I was like, ‘Oh, maybe I’m done.’ And then I met Danny and was like, ‘Alright, I got to pump them out for him,'” the blonde beauty revealed during a Today show appearance in early January. “He needs a boy. He needs his own boy!”

Honestly, we’d love to see a playdate between Kate and Sara’s kiddos!
