Pop star Lady Gaga feels she will always be on her own as she is "married to loneliness".

Asked whether touring makes her lonely, the 25-year-old singer said: "Yes, but I'm supposed to be, I am an artist. We wallow in loneliness and solitude our whole lives in search of the answer to hundreds and millions of questions that run through my mind."

"Yes, I'm lonely. But I'm married to my loneliness," contactmusic.com quoted her as saying.

Gaga - real name Stefani Germanotta - says is always prepared to sacrifice love for her music.

"I would choose my work. I would die without it and I could never be reborn. My biggest fear is missing out on a creative idea because of a lack if time," she said.
