Brooke Shields responded to Meghan Markle‘s story about being 11 years old during the SXSW event in Austin, Texas, on Friday.

Speaking during the Opening Day Keynote Panel, Meghan shared a story about how she took on a sexist TV ad in her youth.

She said: “I was 11 years old. I had seen a commercial for a dishwashing liquid…and the boys in my class said, ‘Yeah that’s where a woman belongs, in the kitchen.’

“And at 11, I just found that infuriating…I wrote letters…and they ended up changing the commercial.”

Shields said immediately following Meghan’s story: “This is one of the ways we differ. When I was 11, I was playing a prostitute. I wish I had known you when I was 11.”

Meghan, 42, spoke alongside Shields, journalist Katie Couric, author Nancy Wang Yuen, and editor Errin Haines during Friday’s panel. Their keynote was titled, “Breaking Barriers, Shaping Narratives: How Women Lead On and Off the Screen.”

The opening day of the event coincides with International Women’s Day, a worldwide celebration of women’s contributions to society.

Hugh Forrest, SXSW’s co-president, said in a statement: “We are so honoured to host this distinguished group on International Women’s Day for a significant discussion on the importance of representation in media and entertainment.”

The panelists discussed women in media, social media’s effect on girls’ mental health, and more. The conference will run through March 15.
