Actress and singer Selena Gomez will call on fans to help her choose ingredients for her upcoming perfume.

The 18-year-old, who is best known for playing Alex Russo in the Disney Channel television series Wizards of Waverly Place, will invite her fans to log on to selenagomezperfumes.com and vote for their preferred ingredients later this autumn.

The first 50,000 entrants will be rewarded with a free sample of the fragrance upon its release, in addition to being entered into a prize draw to win a tour of the fragrance lab with Gomez.

The move is likely to build anticipation for the launch of the scent, securing sales to many of those fans who will feel they will have played an important role in the manufacturing of the product.

The fragrance is expected to go on sale in the spring of 2012.

Gomez’s boyfriend Justin Bieber released his fragrance, entitled 'Someday', earlier this year.
