Jennifer Aniston Was 'A Lot Rounder' When She Was Young, Says Jennifer Aniston

Once upon a time, Jennifer Aniston was what you'd call "chubby." Hard to believe, especially when nowadays women take photos of the A-list actress to their plastic surgeons and say "Like this, please!" but Aniston herself admits she wasn't always this svelte.

At a Self magazine party in honor of Aniston's longtime friend and yoga instructor Mandy Ingber's new book, "Yogalosophy," Aniston told People magazine: "We were a lot rounder. We ate terribly. We did that, and then we sort of grew up a little bit more and we got jobs."

The "we" being Ingber and her, who've been friends for 22 years.

Aniston, 44 -- now a bona fide fitness junkie -- also fessed up to having cheat days. "Cheat days for me are usually ... it's either Mexican food," she said, according to the Los Angeles Times, "maybe Italian pasta, but I think you always have to do it in moderation."

The bride-to-be also spoke about using yoga to keep her calm before her big wedding. Talking to E! News, Aniston said "yoga helps you prepare for everything. It's like meditation. It allows for anything that comes at you during the day to be doable."

Hopefully, Jen isn't too stressed about her upcoming nuptials to Justin Theroux, despite rampant rumors that the two might postpone the wedding because of Aniston's ex, Brad Pitt. According to the Atlantic Wire, the Brangelina summer wedding is putting a cramp in Aniston's stylish ceremony, and in order to avoid being associated with Pitt's big day, Aniston is delaying hers.

Here's hoping she remembers to breathe.
