Lady Gaga's rep is dismissing reports that the singer subsists on baby food in order to stay slim.
Britain's Heat magazine reported that Gaga is "living off baby food -- which is not giving her enough energy to sustain grueling performances."
"Everyone is really worried about Gaga," the source told the gossip magazine. "She's not eating healthily at all. She's substituting meals for jars of baby food."
A rep for Gaga told Gossip Cop the reports are "not true."
For what its worth, her backstage catering rider includes a roast chicken, crackers and cheese, chips and guacamole, dried fruit, bread and peanut butter and jelly -- no mention of baby food.
Jennifer Aniston and Reese Witherspoon have also reportedly also given the diet a try.
