To prove she completed the detox, she uploaded another photo of the empty bottles.

"Done! Detoxed & healthy from @eatpaleta 2 day cleanse. Everything in moderation, people!" she wrote a few days later.

The wife of singer Justin Timberlake also makes sure to incorporate other healthy choices in her daily life.

"For me, getting enough sleep, drinking lots of water, having a healthy diet, and staying away from alcohol are musts," she told Elle magazine in 2011. "It's so boring, I know, but doing those things really helps."

The 31-year-old also exercises to maintain her toned body.

"Yoga is a constant for me because it keeps my muscles long and flexible," she also told the magazine. "But now that summer's coming around, I'm planning on spending more time outdoors playing volleyball and jogging with my dog, Tina."
