Brooke Shields and Fran Drescher go way back.

During an interview with PEOPLE and Entertainment Weekly on the red carpet at the 2025 Screen Actors Guild Awards, Shields, 59, caught sight of the SAG-AFTRA President and invited her to join the fun — while also spilling a secret about their friendship.

"She helped me with my fertility treatments when I was trying to get pregnant," Shields said of Drescher, 67, as she made her way over to join the interview.

"She shot me up," Shields joked of Drescher.

After Drescher joined her longtime friend, she said of helping Shields with her IVF treatments, "That's true, that's true."

Shields welcomed her first born, Rowan, 21, via IVF with her husband Chris Henchy, and has been open about the process — as has Rowan.

Shields' daughters have spoken about how much they admire their mom's candor about in vitro fertilization (IVF) and postpartum depression, which she wrote about in her 2005 book, Down Came the Rain. At the time, she was one of the first high-profile women to share her struggle with feelings of sadness and hopelessness following the birth of her oldest, Rowan, whom she had via IVF.

“My mom went through a lot and IVF too. I wouldn’t be here without IVF," Rowan told PEOPLE earlier this year. "I was frozen for two years and I think Mom talking about it with us from an early age, we are now aware. That’s an important conversation for young women."

Rowan also said, "I don’t want my mother to ever go through anything bad, but when the book came out, it changed a lot of women’s lives."

"There was a beneficial outcome for something so horrible and she now has a stronger connection with me because of what she went through."

Shields told PEOPLE she wrote about her experiences "because no one was talking about it."

"And another thing is — these are two women who may or may not have children but if they did, there’s a potential it could happen [to them]," she said, referring to Rowan and her daughter Grier, 18. "It’s just a tool — to help them know if something is off, that it’s common and should be addressed. Nothing is wrong with them. It’s not their fault, so that is what I wanted to impart to them later in their life."
