Selena Gomez wants her signature scent to be "really romantic".

The singer and 'Monte Carlo' star is working on her new perfume and wants it to help every girl catch the interest of the boy they like.

She told "My perfume right now, I want it to be really romantic, I want it to be sweet and sophisticated.

"I think with anybody, every girl thinks that's the first thing they like, every girl wants to smell great for the boy they like at school or their crush."

The singer has also invited her fans to help her design the perfume, and pick out the base, heart and top notes, from a shortlist she's already compiled.

She added: "I'm creating the basic scent, but I'm inviting my fans to help create the top notes and what goes into it, we're going to pick the top ten and they're going to come into the factory and help with the design.

The first 100,000 fans to visit Selena's website to vote on the favourite fragrance notes will receive a sample of the perfume before it is available in stores.
