Ariana Grande shuts down rumors that she suffers an eating disorder. The "Victorious" actress explains in her Tumblr account, "Yes, I lost a bit of weight last year," but "it's because I stopped eating junk food and started making healthy choices."

"I was happy with the way I was before and I'm still happy now! Just healthier!" she continues. "The lifestyle change I chose to make last August is not and was never about being skinnier. ... This is about making sure the foods you put in your body will nourish you and be put to good use."

"The reason why I lost as much weight as I did is because I used to live on junk food. Like around the clock. So I drastically changed my eating habits, started exercising daily and I'm all around a healthier me. I'm eating as much as I was before just the content has changed."

"And the way I'm eating now actually helped even out my blood sugar. As some of you guys may know I've struggled with awful hypoglycemia for my whole life and it's improved a ton since I changed my eating habits. Also, I've been coming up with these really fun, healthy, completely organic homemade snack recipes after work. I'll share some of them on Tumblr soon."

The Nickelodeon star also addresses question about her religion after she was spotted wearing a Kabbalah red string. "I was born Roman Catholic and I still go to church sometimes and of course celebrate Christmas and Easter," she explains. "But when I was 12 years old I used to practice Kabbalah at the Kabbalah center in Boca and of course I wore 'The Red String.' "

"I decided to pick it back up a couple of months ago because I really loved doing it but I never really said anything publicly about it because I didn't really feel the need to. As an entertainer I'm always kinda scared when it comes to talking about religion or politics because I just feel like it's not my place."
