The 38-year-old actress, however, is not yet ready to don a bikini, reported Daily Star.
"I'd rather kill myself than get into a bikini right now!... I take care of myself, but I'm never going to be the person who talks about diet and exercise. I would fail that conversation!," she said.
Barrymore also opened up about the changes she experienced as a mother-to-be.
"I got a wonderful little goatee, and it was red! I also got hyperpigmentation on my cheeks," she said.
