Lady GaGa Applause ARTPOP

Lady Gaga never gets drunk - because she is too focused on her career.

The singer claims she doesn't go out and party hard because she doesn't want a hangover affecting her work and she struggles to motivate herself to go clubbing.

She said: "I don't go to nightclubs. You don't see pictures of me falling out of a club drunk. I don't go - and that's because I usually go and then, you know, a whiskey and a half into it, I got to get back to work. Because I amor my work so much, I find it really hard to go out and have a good time."

Lady Gaga has revealed new song "Telephone" - which features on her latest album "The Fame Monster" - is about her strict work ethic and fear of fun.

She told MTV: "Something that I have or fear is never being able to enjoy myself. That's my fear - that the phone's ringing and my head's ringing. Whether it's a telephone or it's just the thoughts in your head, that's another fear."
