Brian Austin Green says he doesn't mind if his son Noah wears dresses.
"My son, he's four," Green told host Dax Holt. "I've heard from some people that they don't agree. They don't agree with him wearing dresses. To them I say, 'I don't care.'"
"He's four and if he wants to wear it, then he wears it," he explained. "It's dresses or goggles or slippers, whatever. It's his life. They're not my clothes."
"At four, at five, that's a time when he should be having fun," the star added. "He's not harming anyone [by] wearing a dress. So if he wants to wear a dress, good on him."
Noah has dressed up as Snow White and as Elsa from "Frozen," in addition to wearing everyday dresses. Social media users criticized Fox after she posted a photo of her son in a dress over the summer.
"It's clear that Megan Fox wanted a daughter but got a son instead, so she makes him dress like a girl," one person tweeted.
"Your boy MUST be a MAN, what a shameful time to grow up," another person wrote on Instagram.
Green also shares 3-year-old son Bodhi and 13-month-old son Journey with Fox, whom he married in 2010.
He previously told Hollywood Pipeline he's open to having a fourth child if the baby was a girl.
