Jessie J says rumors of her being a lesbian are totally untrue.

In a new unauthorized biography, written by Chloe Govan, the author claims that the “Price Tag” singer is a lesbian, but was told to hide her sexuality so as to keep her commercial appeal.

In the book, Jessie J: Who’s Laughing Now, Govan says that Jessie was told by record executive that she would be more appealing to fans if she said that she was bisexual instead of a lesbian.

“Jessie might have been with boys in the past – but she is 100 per cent gay. Jessie was openly lesbian and didn’t hide it,” claims the author.

“She was advised not to come out, though. Certain people thought being bi was trendy, exotic and a fashion statement. It would increase her allure.”

Jessie has since joked about the new allegations saying on her Twitter, “What’s that?! *whispers because its a secret* I’m really a lesbian?! Ha! Thanks for writing yet another boring untrue story. I thought I was still dating Tinie, NO Ellie G, NO Mark Wright….bla bla bla!”

Jessie has always been an open bisexual woman.

Last year Jessie revealed “I’ve never denied it. Whoopie doo guys, yes, I’ve dated girls and I’ve dated boys – get over it. If I meet someone and I like them, I don’t care if they’re a boy or a girl.”

Do your thing Jessie J!
