Before Jennifer revealed it all, she sat down with Ellen to talk all things parties. She's turning the big 5-0 this July and plans to celebrate...with the whole country. “My birthday’s in July and so this summer I decided I wanted to do something big for my birthday since it is a big birthday," she shared. "I’m going on a US tour called “It’s My Party.” The tour will consist of 25 shows as of now and will take place this summer.

She also opened up about her no carb and no sugar challenge she did with Alex a few weeks ago. “It was really hard," she said. "Not only do you get a headache, but you feel like you’re in an alternate reality or universe. You don’t feel like yourself." Although it's tough in the beginning, the singer promises that it'll make you feel good about yourself in the end. “It takes down the inflammation and it feels good."

And there's a reason she went on that super strict diet—she's gearing up for her next role. "I’m getting ready for this movie that I’m going to do called Hustlers," she revealed. "And I have to play a stripper. So I’m getting ready for that."
