The 24-year-old singer ' who has previously raised concerns about casual sex hurting her ability to be creative ' admits she likes to keep physical acts of love to those close to her.

She told AMP Radio: ' have weird superstitions about sex. If you're not having sex with someone who really cares about you or who really loves you they can screw up your energy.

' think sometimes, I don't know, if you are promiscuous and are just sleeping around that people can take things from you. I think it's always important to be making love.'

The 'Alejandro' singer is believed to have got back into a relationship with ex-boyfriend Luc Carl recently, despite him having a girlfriend when she went back to the New York bar she used to work at to meet him

A source said: 'Luc was like the cat that got the cream. He had the most famous woman in the world vying for his attention and a hot young blonde waiting in the wings.

"It could have ended really badly, but the other girl melted into the background. She knows what Luc's like - he has women all over the place... Gaga has convinced herself that this time she's got Luc back for good.'
