Cameron Diaz Chugs Bottled Water in the Morning to Poop!

Cameron Diaz attends a signing of her new book “The Body Book” at the Barnes & Noble bookstore at The Grove on Thursday (January 16) in Los Angeles.

The 41-year-old entertainer made an appearance on The Dr. Oz Show this week to promote the book and she revealed that she chugs water every morning to help her poop!

“This is the best way for me to go poop in the morning,” Cameron said while holding up her bottle of water. “Water wakes you up.”

“First, I brush my teeth because I don’t want to swallow all the bacteria in my teeth from the night before,” Cameron added. “So I make sure that’s gone and then…” she said before starting to chug the entire bottle down. Watch below!
