"Her mum thinks she drinks too much and doesn't eat enough," a source told The Sun. "She has gone along to keep an eye on her boozing and feed her up."

Gaga's weight has yo-yo'd over the last several years. In fact, after putting on some weight during her European tour, Gaga debuted a dramatically slimmed down physique in her "Born This Way" video.

Cynthia Germanotta, 56, is apparently staying on Gaga's tour bus to make sure she stays away from her "drunk diet," which she recently extolled the virtues of.

"I am on the drunk diet," Gaga revealed in a recent interview. "I live my life as I want to, creatively. I like to drink whiskey and stuff while I am working. But the deal is I've got to work out every day, and I work out hung over if I am hung over. And it's about the cross-training and keeping yourself inspired. I have to say, I do a ton of yoga."

But it seems like Gaga's got an even healthier plan thanks to Mama Gaga. "She may be one of the biggest, and strangest, pop stars in the world but her relationship with her parents is very traditional," a source said of Gaga's mom being on tour.
