Actress Susan Sarandon says her son “colors outside the lines” when it comes to gender expression, and she’s perfectly OK with that.

The Oscar-winner, 68, opened up about her 23-year-old son, Miles Robbins, during a June 15 appearance at the TrevorLIVE, The Trevor Project’s annual fundraiser.

“My son Miles is a musician and a DJ,” she told People magazine. “And sometimes when his band performs they all wear dresses, and he has long hair.”

Sarandon went on to note that Miles’ willingness to break stereotypes had her full support. “I think the more crayons you have in your box to color outside the lines, the more exciting it is,” she said.

The “Thelma and Louise” star has been a longtime supporter of The Trevor Project, a lesbian, gay, bisexual and transgender (LGBT) youth advocacy organization, and said motherhood has motivated her ongoing support.

“As a mother, I know how difficult it is to survive the teenage years intact and the socialization process — if you step out of line, it’s so difficult,” Sarandon, who is slated to play the lesbian grandmother of a transgender teen in the upcoming film, “Three Generations,” told the publication. “And there are so many kids these days who are questioning, gay or transgender, who have a very tough time and it could be very dangerous for them.”

Earlier this month, Sarandon discussed gender identity in today’s evolving society in a candid interview on “Oprah’s Master Class,” saying she was “so excited” by the “fluidity of gender that’s happening” in today’s evolving society.

“I think once all those ‘boxes’ are gone, it’s going to be so much more interesting and so much less energy spent on those ‘boxes,'” she said. “We can get down to the nitty-gritty of, really, what a person is.”
