Lady Gaga thinks she is "married to loneliness".

The 'Edge of Glory' hitmaker - who has been in an on/off relationship with barman Luc Carl throughout her career - is convinced she will always be on her own because "wallowing in solitude" is what gives her artistic integrity.

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."

Gaga - real name Stefani Germanotta - would always be prepared to sacrifice love for her music, as she would "die" if she wasn't able to release songs into the world.

Asked whether she would pick fame or love if she could only have one, she told Asia's Star TV: "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."
