Jennifer Aniston has reportedly been sticking to a rigorous diet and exercise plan in anticipation of her upcoming wedding to longtime boyfriend Justin Theroux, and while she has stated that she wants to be five pounds lighter, the 45-year old We’re the Millers star is still in fantastic shape. During her appearance on Jimmy Kimmel Live on Aug. 27, Aniston reprised her Friends role alongside former co-stars Courteney Cox and Lisa Kudrow, and showed audiences how well she has maintained her youth and beauty since the popular series ended over a decade ago.

Aniston reluctantly agreed to act out a fan fiction supposedly written by Kimmel on his talk-show Wednesday night, which had her reprise her role of Rachel in an exact replica of the sitcom’s famous kitchen set. Kimmel acted out the part of Ross, and shamelessly hit on Aniston before Cox and Kudrow appeared, also reprising their infamous characters. While Cox and Kudrow have undeniably aged since the show came off the air in May 2004, Aniston appeared visibly unchanged, despite her refusal to don the Rachel wig for the skit.

While Aniston didn’t reveal her beauty secrets on the talk show, she did hint at one peculiar item in her diet – Kimmel’s wife Molly McNearney’s breast milk.

“It’s like the one milk you don’t have to feel guilty about drinking,” said Aniston. “It’s like no, that dairy is OK. But I had some of Molly’s.”

“I didn’t know if you wanted me to mention that but you did have some. You breastfed my wife,” said Kimmel.

“I didn’t breastfeed her. She breastfed me! It’s sweet, it’s almost coconut-milky,” laughed Aniston. “Come on, someone must’ve tasted breast milk in this audience?”

Earlier that day, Aniston used an appearance on the Today Show to express her happiness with life and debunk tabloid claims that not having a child causes her to feel unfulfilled.

“I don’t have this sort of checklist of things that have to be done, and if they’re not checked, then I’ve failed some part of my feminism or my value as a woman because I haven’t birthed a child,” she insisted. “I’ve birthed a lot of things, and I feel like I’ve mothered many things. And I don’t feel it’s fair to put that pressure on people.”
