According to Accesshollywood.com, former actress now journalist Shirley MacLaine, asked some of her co-stars in the movie Valentine's Day what their eating habits are:

“I would like to ask all the [women] up here what they eat?” Shirley asked, according to AOL’s PopEater. “I’d like to have a rundown. Do you diet all the time? You’re looking so fabulous. Is it worth it?”

After a brief bit of silence, Julia Roberts reportedly spoke first, turning the attention on some of her younger co-stars.

“You girls are slim,” Julia said. Eventually, Jennifer Garner reportedly also spoke up.

“I’m nursing,” the mom of two said. “As soon as I’m done I’ll puff right back up.”

“I’ll stay tuned for that,” Julia responded.

Other slim stars of “Valentine’s Day” include Jessica Alba, Jessica Biel and Anne Hathaway.
