Lady Gaga has been outspoken in her crusade against bullying, starting the Born This Way Foundation, whose mission statement is “to foster a more accepting society, where differences are embraced and individuality is celebrated” and whose stated end goal is to create “a braver, kinder world.”

But Gaga seems to have stepped into controversy this week when she Tweeted about her new fitness routine while gearing up for her European Born This Way tour.

Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger #PopSingersDontEat #IWasBornThisWay

Many fans did not react well to the #PopSingersDontEat hash tag.

@ladygaga not the best message to promote…

@ladygaga I love you with my heart, but what the hell!? “Pop singers don’t eat”… I want to sing. I have an ED. Not very encouraging, Gaga.

It was wrong for Lady Gaga to tweet #popsingersdonteat. Respect = gone.

Many fans have voiced concern back to Gaga via Twitter that she is promoting eating disorders and that the comment is not congruous with her message of acceptance. Gaga admitted to Vanity Fair in a 2010 interview that she battled bulimia early in her career.

The National Eating Disorders Association commented as well, Tweeting out a link and asking, “What’s up with Lady Gaga’s #PopSingersDontEat Tweet?”

Gaga has not commented further.
