Lady Gaga is scared of using a mobile phone due to the rumoured health risks, it's been reported.

The singer, who released a song called 'Telephone', is apparently worried that she might develop a brain tumour.

According to The Sun, a member of her entourage now dials numbers for her and then holds the phone away from her head when she speaks.

"Even though there's no firm evidence, it's really freaked her out,” a source told The Sun.

"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."

Meanwhile, Lady Gaga debuted a new song during a concert in the US last night.

Currently, it is not known if piano-led ballad, entitled 'Living On The Radio', will be released as a single.
