Lady Gaga has explained the 'blood and semen' content in her new fragrance.

"It was taken out of my own blood sample, so it's a sense of having me on your skin," she told Australian radio hosts Kyle and Jackie O, according to Fashionista.

In January, the pop star caused a fracas when she said she wanted her new perfume to smell like "blood and semen."

"I wanted to extract the feeling and the scent of blood and semen from molecular structures, so that's where that [report] came from," the New York Daily News quoted her as saying.

"[Blood and semen] is in the perfume but it doesn't smell like that - you just get the after-feeling of sex from the semen and the blood is primal.

"The perfume smells like an expensive hooker," she added.

The star's seminal fragrance is set to hit shelves next year. (ANI)
