A former bodyguard is suing Britney Spears for sexual harassment, claiming the singer subjected him to "repeated unwanted sexual advances."

Fernando Flores filed the sexual harassment lawsuit in suburban Los Angeles on Wednesday, alleging the singer intentionally inflicted emotional distress.

His statement of claim also makes controversial allegations about Spears's treatment of her two children, saying Flores saw her whip the boys with his belt and act inappropriately in front of them.

Flores worked for Spears from February to July of this year. His lawsuit claims that Spears, among other things, exposed herself to him and summoned him to her bedroom while she was naked.

Flores's allegations have not been proven in court.

In a statement on her website Thursday, Spears denied the accusations that she sexually harassed him and abused her children.

The statement said Spears and her attorneys expect the case to be dismissed.

An attorney for Kevin Federline, Spears's ex-husband, called the child abuse claims baseless and motivated by money.

Mark Vincent Kaplan said Flores's accusations had been investigated before the suit was filed and warranted no action. He said Federline takes any allegations of abuse or wrongdoing regarding the former couple's children seriously.

"He is satisfied that the allegations are a product of economic motives," Kaplan said. "They are as baseless as they seem."

Federline has custody of their sons, Sean Preston and Jayden James, but Spears has substantial visitation.

Kaplan said if Federline believed the children were in danger, he would have stepped in already.

He noted that Flores's lawsuit was leaked to online news outlets before the suit was filed.

"I think that the timing of this and the nature of the allegations speak for themselves."

The lawsuit seeks unspecified damages from Spears and the bodyguard's former employer, Advanced Security Concepts Corp.

Spears remains under a court-ordered conservatorship in which her personal and financial affairs are controlled by her father and an attorney and monitored by a judge.

The conservatorship has prevented her from being deposed or testifying during previous cases in which she was sued.

After a high-profile custody battle, Spears and Federline reached an agreement on custody of their boys in 2008.
