Katy Perry has topped the poll in the search for the perfect person to sing a romantic duet with this Valentine's Day.

The I Kissed A Girl star hit the right note with men and women coming top of the poll with both sexes, getting 15% of male votes and 10% of the female vote.

The next most popular partners for men were Rihanna (9%) and Shakira (7%), with women singers saying they wanted to share a stage with Gary Barlow (9%) and The Killers frontman Brandon Flowers (7%).

The poll of 100,000 karaoke fans was carried out by luckyvoice.com.

The firm's managing director, Nick Thistleton, said: "Katy Perry is a fantastic talent with a superb voice - however we had imagined it would have been the likes of Justin Bieber or Justin Timberlake who were vying for the number one spot with the girls."

Katy and comic Russell Brand announced their marriage was over at the end of last year.
