Lady GaGa took an HIV test after panicking about her behaviour on tour.

The 'Bad Romance' singer recently had a sexual health screening in New York because she "forgot" to look after her body properly when she was performing live shows for The Monster Ball Tour concerts.

She said: "I had an HIV test two days ago - and it's not because I'm taking off my clothes every night with a different man. When I'm on the road, I forget about taking care of my body. I don't go to the doctor as regularly as if I were in one place all the time. So I woke up and thought, 'Oh, I'm home in New York. I'm going to see my gyno and I'm getting an HIV test.' "

The 23-year-old star - who is believed to be dating her stylist and friend Matthew Williams - has made it her personal mission to make it "fashionable" for women to carry condoms and practise safe sex.

She told MarieClaire.com: "You put that condom in your purse and save your own f**king life. And don't call me in a week and cry. Because you know that infamous call from your girlfriend - 'Oh, my God, I got caught up, and I was afraid he wouldn't like me.' I mean, what year is it? It's scary, but I want it to be fashionable to be smart."

Lady Gaga recently blasted contradictory attitudes to sexuality which let men be more vocal about their conquests than women.

She said: "When a guy says, 'Oh I f**ked all these chicks this week', there's a high-five and giggling. But when a woman does it and it's publicised or she's open about her sexuality or she's free or liberated, it's 'Oh, she must have a d**k'. There's a threat."
