Simon Cowell sings Power Rangers theme song for IDF fundraiser

It's not every day you get to hear X-Factor judge Simon Cowell sing.

But he did just that at an Oct. 22 fundraiser for the Friends of the Israel Defence Forces, which ultimately raised $20 million at its Los Angeles gala, attended by stars such as Cowell and Lionel Richie.

Cowell donated $150,000 of his own money to the Friends of the IDF group, which helps with the well-being and education of IDF soldiers, including those from the Lone Soldier program, which helps soldiers whose families lives abroad, as well as those who come from abroad to fight with the IDF.

But Cowell's contribution grew when he joined billionaire Power Rangers creator Haim Saban in singing the theme song. Saban offered the Friends of the IDF $1 million if Cowell would join in. Though after a single line, Cowell said he would donate another $100,000 if he could stop singing it. They eventually settled on a $250,000 exit fee.

The Jewish daily Forward reported that a $4.5-million donation from the International Fellowship of Christians and Jews helped the Friends of the IDF reach the $20-million mark.

Cowell's father was Jewish, a fact he reportedly never discussed with Cowell, and Cowell is expecting a child with his Jewish girlfriend, Lauren Silverman, in February.
