Singer Lady GaGa is reportedly afraid to use her mobile phone because she thinks it will damage her brain.
According to The Sun, the popstar doesn't even carry around her own phone, instead getting one of her entourage to hang onto it for her.
When she needs to make calls she gets an assistant to dial for her and hold the phone up for her to speak into.
A source said: "Even though there's no firm evidence, it's really freaked her out."
"One of her team has to hold the phone so it isn't too close to her head. She then listens on the phone loudspeaker."
