Lopez's rockin' bod is due to the Optimal Cleanse from East West Essentials.The "American Idol" judge said, "My nutritionist loves this, she was like, 'I can't believe you mentioned the Optimal Cleanse!' It's a really good cleanse. This is something that actually cleans out your intestines and everything that builds up, you feel much lighter, and of course, you do drop a few pounds. You can do it for 10 days, but I do it for five days when I feel like I need a break from eating bad."For more information on the Optimal Cleanse, go to EastWestEssentials.com [http://www.eastwestessentials.com/]
