Lady GaGa's friends are terrified she's heading for a breakdown.

The 'Poker Face' singer - real name Stefani Germanotta - recently split from boyfriend Speedy and her pals are now concerned whether she is coping with that along with the other pressures she has in her life.

One told Britain's Look magazine: "Everything seems to have gone wrong at once for her. She split up with Speedy last month and since then I think the toll of relentless touring and promotion over the past year has hit her.

"We're worried she is going to have a breakdown if she keeps going on like this. She's clearly heartbroken and exhausted and she should slow down and look after herself. But even though she says she's ruined her life, it's as if she's addicted to the fame."

Last week, the 23-year-old blonde claimed fame had ruined her life and can't deal with the pressures it brings.

She said: "If anyone had told me at the start of my career what success brings with it, I would have thought twice about it. Now I know you have to choose between fame and love. Both don't work together."
