Drew Barrymore may admit she doesn't have a bikini body but she's totally fine with it.

Entertainment Tonight reports the 40-year-old actress opened up about how she deals with her body image in her interview with InStyle magazine's November issue.

"I am who I am and I just don't have a bikini body. I don't even have a one piece body anymore! But I am loving the long rash guard, board-shorts look," Barrymore said.

"I've beaten myself up about not being a certain thing," she explained. "If someone says, 'Let's go to the beach today,' my first thought is, 'F--, what am I going to wear?' I remember when Amy Schumer was on Ellen, she called her midsection a 'lava lamp.' I thought, 'That was perfect! That's what I've been trying to say.' But then I saw her in Trainwreck, and she looked so good in a tiny bra and short skirt. I was like, 'No, you don't have a lava lamp.'"

The mother of two who started out as a child star added she has other priorities that are way more important than achieving the perfect beach look. Barrymore has shifted her life from being a busy actress to a full-time mom to daughters three-year-old Olive and one-year-old Frankie with his actor-husband Will Kopelman.

"I'm not going to pretend to my daughters that I'm pure as the driven snow... The best I can do is open up my heart to them," she said. "That's soul-baring enough. Making bad decisions doesn't make you a bad person. It is how you learn to make better choices."

Barrymore also wrote her life-lessons in her new book, Wildflower, which is set to be published this month.

"I've always wanted to write and I never had the discipline or the objectivity to write in the way I was able to do," she said about being an author. "I think you will be very surprised."
