Lady Gaga avoids having sex because she is afraid it will lessen her creativity.

The 'Alejandro' singer - who has recently rekindled her romance with former boyfriend, New York barman Luc Carl - thinks regular lovemaking could have a negative effect on her art.

She told Vanity Fair magazine: "I do f**k, but I'm certainly not promiscuous. I have this weird thing that if I sleep with someone they're going to take my creativity from me through my vagina."

And Gaga - real name Stefani Germanotta - is afraid to be in a relationship because she finds it hard to trust people.

The 24-year-old pop star explained: "I'm perpetually lonely. I'm lonely when I'm in relationships. It's my condition as an artist."

Gaga has also lifted the lid on hit single 'Bad Romance' - admitting the title and lyrics are inspired by her own life.

She said: "I'm drawn to bad romances. And my song ['Bad Romance'] is about whether I go after those [sort of relationships] or if they find me."
