Jessie J's record sales have risen by 89% since she joined the BBC's new talent show The Voice.
The 'Who's Laughing Now' singer has experienced a high rise in sales of her debut album Who You Are since joining The X Factor's rival show in March.
"So far Jessie has seen the biggest lift - with sales of her album nearly 100% up on the period before the show started," Gennaro Castaldo, head of press and PR at HMV told the Radio Times.
Meanwhile, Jessie's fellow coach will.i.am has seen a rise in sale of records by his group the Black Eyed Peas. He is due to release his debut album #willpower later this year.
This week, Jessie was forced to deny claims that she is a lesbian, following claims made in an unauthorised book that she was forced to lie about her sexuality.
