It’s no secret we enjoy living vicariously through celebrities around here. From their interior designs to their beauty secrets and even their holiday traditions, we love taking a peek inside the lives of the rich and famous. But no one takes it further than Rebecca Harrington, author of the recently-released and totally hilarious I’ll Have What She’s Having.

In the book, she braves 14 bizarre diets and workouts of beauties like Beyoncé, Marilyn Monroe and Pippa Middleton. We may have sampled a GOOP-y recipe or two, but Rebecca channeled Gwynnie for 10 whole days (earning a rash and a sense of superiority). She is THE expert in celebrity cleanses, indulgences and exercise regimens, and she’s here to tell us about her adventures in celebrity diets.


What was the first celebrity diet you tried, and what inspired you to keep trying more?

I first tried the William Howard Taft diet, a terrible, high-protein diet from 1905. When that was deemed impracticable (by me), I branched out to more temperate dieting climes — Liz Taylor and Gwyneth Paltrow.

In the book, you talk about how Marilyn Monroe drank raw eggs and warm milk, and Elizabeth Taylor put peanut butter on her steak. Is there anywhere you’ll draw the line when it comes to a weird recipe?

No! I’m a daredevil.

Whose recipes were the simplest to make?

Beyoncé’s. The Master Cleanse is a very simple, lemonade-based diet she went on for several days in preparation for Dreamgirls. Unfortunately, the only thing you consume is lemonade.

Whose diet surprised you the most? Did you think one would be better/worse than it was?

Gwyneth Paltrow’s was way better than I thought it would be. The recipes were delicious! I could have stayed on that diet forever. (If I was a millionaire — it was rather expensive!)

Whose exercise regimen has been the most effective, and whose has been the most insane?

Madonna’s are probably the most effective regimens, but they are also the hardest. I could barely do them!

Your friends haven’t always loved your diets (Gwyneth’s meatballs come to mind). How do you stay social in the middle of a celeb diet?

I don’t! You kind of have to resign yourself to the fact that your friends may not want to hang out with you for a couple of days.

Are there any favorite recipes you find yourself making even when you’re not on the diet?

I do like green juice now. It’s sort of refreshing in a grassy way.

Which celebrity diet secrets do you most want to try next?

Ooo! Maybe Rihanna’s? Or Grace Kelly’s?

What’s one piece of advice you’d give to anyone trying a celebrity diet?

Stay strong, but also feel free to give up.

And any advice for the celebrities themselves?

You poor people! I’m sorry for you.
