Freddie Mercury's secret daughter comes to light

A new biography about late Queen frontman Freddie Mercury will be unveiling his relationship with a secret daughter.

The woman, now 48, is only disclosing herself as B in the book being written by rock biographer Lesley-Ann Jones.

B is said to be working in the medical field somewhere in Europe and was conceived in 1976 when Mercury had an affair with the wife of one of his close friends, Daily Mail reports.

Titled Love, Freddie, the book is set to reveal the woman's close relationship with the rockstar until the singer's death in 1991.

The woman claims that Mercury gave her 17 volumes of his personal journals, which she kept secret for decades.

"Freddie Mercury was and is my father," B says in the yet to be published book. "We had a very close and loving relationship from the moment I was born and throughout the final 15 years of his life."

"He adored me and was devoted to me. The circumstances of my birth may seem, by most people’s standards, unusual and even outrageous.

"That should come as no surprise. It never detracted from his commitment to love and look after me. He cherished me like a treasured possession."

Mercury's inner circle of friends is said to have known of her existence all along.

The woman also addresses why she has decided to share her story now after decades of secrecy.

"After more than three decades of lies, speculation, and distortion, it is time to let Freddie speak.

"Those who have been aware of my existence kept his greatest secret out of loyalty to Freddie."

"That I choose to reveal myself in my own midlife is my decision and mine alone. I have not, at any point, been coerced into doing this."

"He entrusted his collection of private notebooks to me, his only child and his next of kin, the written record of his private thoughts, memories, and feelings about everything he had experienced."

Author Jones also opened up about her initial doubts about covering B's story.

“My instinct was to doubt everything, but I am absolutely sure she is not a fantasist. No one could have faked all this. Why would she have worked with me for three and a half years, never demanding anything?" the author told Daily Mail.
