TV host and celebrity daughter Kelly Osbourne has said she is tested four times a year for sexually transmitted infections (STIs).
The daughter of former Black Sabbath frontman Ozzy Osbourne admitted having unprotected sex in the past but said she had the tests for her own peace of mind.
Recently-married Scarlett Johansson has previously said she has two HIV tests a year, and said that anyone who did not was "disgusting".
Ms Osbourne told New! magazine that she saw her first condom when she was around seven, on her father's tour.
The 23-year-old said: "I was on tour with my dad and at every single one of his shows, they hand out free condoms.
"I was about seven or eight and I picked up a packet and was like, 'Mum, what's this?'
"She had to explain to me what they were. It was something my parents had never been shy about. They always told us what they think and that we should protect ourselves."
Ms Osbourne, who is dating model Luke Worrall and is an ambassador for World Contraception Day, said: "I go three, maybe four times a year to get tested (for sexually transmitted infections) and most of the time I don't even need to. I just go for peace of mind."
