Lady Gaga's friends leave "mounds of cheeseburgers" in her dressing room because they know she can't eat them.
Very often they make jokes about my diet, because I have to stay so in shape for music videos and performances, they play jokes like leaving mounds of cheeseburgers in my dressing room and stuff. It's really awful. It's vicious
The 'Judas' singer likes to take her friends as support acts on tour, but said they play cruel tricks on her, like leaving her junk food treats she can't indulge in, due to her strict diet.
In a Google Moderator interview - which saw her answer questions submitted by fans - she explained: "I don't like surprises and I don't like pranks.
"But I have had very few famous acts open for me, it's mostly been underground acts and DJs, people that I've known since I was 18.

Gaga, 24, is said to have used extreme dieting methods to stay slim early on in her career.
In Maureen Callahan's 2010 book 'Poker Face: The Rise and Rise of Lady Gaga', the musician's former tour manager David Ciemny claimed she would binge on junk food such as cakes and sweets, then not eat for weeks to fit into her costumes - once allegedly losing 20lbs between fittings for one of her outfits.
Describing her food habits, David said: "When I say she was sick, I mean physically and mentally."
Talent scout Wendy Starland added in the text: "The pressure on her to lose weight was very high."
