London: British pop star Jessie J has opened up about her sexual orientation and revealed that she was not a bisexual. She took to Twitter to clarify doubts over her sexual orientation after a new, unauthorised biography on her -- "Who`s Laughing Now" by author Chloe Govan claimed she was bisexual.

The singer branded the report as boring and untrue on her Twitter account, reports a website."It`s funny how many people I`ve dated slept (sic) with that I`ve never even met according to the tabloids. But what`s that?! *whispers because its a secret* I`m really a lesbian?! Ha! "Thanks for writing yet another boring untrue story," she posted.

"I thought I was still dating Tinie (Tempah), NO Ellie G (Goulding), NO Mark Wright... bla bla bla! cantkeepup none of its true," she added.According to the writer of the biography, Jessie J was told to keep quiet about her love life for fear of alienating fans.

"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. She was advised not to come out though," Govan said. Certain people thought being bi was trendy, exotic and a fashion statement. It would increase her allure. Being gay would alienate people," the writer added.
