Los Angeles, Aug 7 (IANS): Katy Perry finds vanilla an "aphrodisiac", and that's why she put hints of the scent in her new fragrance, Mad Potion.

The “Dark horse” hitmaker -- who is rumoured to have reunited with on/off boyfriend John Mayer -- has carefully chosen the scents of her new fragrance, Mad Potion, and it has the sweeter tones because they put her in the mood for love.

"Vanilla, for me, is an aphrodisiac and musk is kind of androgynous, and I like that combination because it's mysterious,” Perry was quoted as saying by Look magazine, reports femalefirst.co.uk.

Perry is fascinated by fragrances and catching a whiff of a particular scent often sends her back in time.

"I love creative, really distinctive, scents that hopefully leave lasting impressions on people. They can sort of time-travel.

"I believe fragrance is a sixth sense, that it makes memories. For instance, if you get in an elevator and smell something someone is wearing that reminds you of the first scent you wore when you were a teenager, or your first boyfriends, I can almost be transported back into that time by a certain smell,” she added.
