Aniston made the surprising revelation during her appearance on Kimmel's TV show to promote her new movie Life of Crime on Wednesday, Aug. 27.
And, unlike her former Friends character Rachel in the hit sitcom, who freaked out when Joey and Phoebe tasted breast milk in the show almost 20 years ago, Aniston, 45, says she’s a fan.
"It’s like the one milk you don’t have to feel guilty about drinking," the actress told Kimmel. "It’s like no, that dairy is okay. But I had some of Molly’s."
"I didn’t know if you wanted me to mention that but you did have some," the talk show host responded. "You breastfed my wife."
"I didn’t breastfeed her. She breastfed me!" Aniston replied. "It's sweet, it’s almost coconut-milky. Come on, someone must've tasted breast milk in this audience?"
Aniston then revealed that not only she not squeamish about drinking breast milk, she's also completely cool when it comes to witnessing births.
"I’ve been to many of my girlfriends’ deliveries," the engaged actress revealed. "I think it’s extraordinary, it’s a miracle."
