Amy Adams talks Miss Piggy!

Amy Adams says Miss Piggy has been her most formidable costar to date.

The 37-year-old actress has worked with the likes of Hollywood legend Meryl Streep but says working with a puppet pig on the new Muppet Movie was far more nerve-wracking.

“Miss Piggy is a formidable character,” says Amy.

“I was in awe. The important thing to remember about Miss Piggy is to just give her a lot of compliments, don’t flirt with Kermit, and always treat her like she’s the biggest star in the room. So understanding those rules, we got along just fine. By watching her I learned that by eating a lot of donuts before a take you’ll have extra energy.”

Amy who has an 18-month-old daughter, Aviana, with fiance Darren Le Gallo recently admitted she doesn’t make motherhood seem easy.

“I’m definitely not one of those women who make [motherhood] look easy,” she said.

“I’m always running late and look, there’s guacamole on my purse! But I’m more patient than I ever thought I would be, and I’m not hard on myself anymore.”
