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."
