Jennifer Lopez Follows in Beyonce & Jay Z's Footsteps, Completes 22-Day Vegan Challenge

Jennifer Lopez wears a comfy sweatsuit for a post-Idol dinner with her beau Casper Smart at Craig’s on Tuesday evening (May 20) in West Hollywood, Calif.

The next day, the 44-year-old entertainer went on Ryan Seacrest‘s radio show and disclosed she did the 22-day Vegan challenge that Beyonce and Jay Z completed together.

“I did the vegan 22-day plan and it was really good and I kept on with it for a few more weeks, and now I’ve incorporated a little bit of fish here and there,” JLo shared. “But I’ve got to tell you I enjoy it. I enjoy eating that way. I never did. And I didn’t know how good you can feel when you put healthy stuff in your body.”
