Britney Spears’s former bodyguard is planning a tell-all book in which he will reveal the singer’s kinky sex secrets.

Fernando Flores, 31, who worked for the star for five months in 2010, said she engaged in threesomes, orgies and lesbian snogs during her wild tours.

And he said he had lined up a million-dollar deal with a major publisher.

The release would coincide with Britney’s third marriage to Jason Trawick reported The Sun.

The former policeman reportedly told a friend: “Britney has a huge sexual appetite and, from what she told me, her tours were an anything-goes environment.

“I heard stories of threesomes, orgies, girls making out – things that would make your hair stand on end.

“She had a lot of young, attractive dancers around her on tour, and things would get crazy. There was drinking, drugs, steamy sessions in hot tubs, all sorts of things.”

Britney and Christina Aguilera famously shared a kiss with Madonna on stage at the 2003 Video Music Awards.

He said the mother of two once told him about a lesbian session with a group of women.

“I was in her bathroom and saw this picture of her in a tub with some girls. It was very sexual. She told me, ‘That was on tour and s*** got crazy.’”

“I asked what she meant and she said they all got it on – she and the girls.”

Flores is suing the star for sexual harassment, saying she repeatedly stripped in front of him and tried to bed him.

He also says he saw the singer engage in inappropriate conduct around her young sons and once borrowed his belt to discipline them.

Flores is seeking unspecified damages from the Grammy Award-winner and his former employer, Advanced Security Concepts.

He launched the case in 2010 and is due to be heard in court this year.

But her team have pledged to fight his claims. Last night a spokesman denied the latest allegations, according to The Sun.

Britney reportedly plans to marry later this year, when her legal troubles are wrapped up, RadarOnline.com reported today.

Trawick proposed last month, just before his 40th birthday.

“She wants to begin her life with Jason on a fresh clean slate,” the website reported.

Britney was first married in 2004, to childhood friend Jason Alexander but the marriage only lasted 55 hours.

Her second was to rapper-dancer Kevin Federline, with whom she has two sons. The couple divorced in 2007 after three years together. – Daily Mail
