Jerry Seinfeld was offered a massive $100 million contract to film one more season of "Seinfeld," but the funnyman turned the deal down because he wanted to have a family, according to his former boss.

The hit sitcom ran for nine series before coming to an end in 1998 and former NBC executive Warren Littlefield has revealed TV chiefs were desperate to persuade Seinfeld to film a 10th season.

They offered him $100 million to stay on, but the star walked away because he felt his personal life was suffering.

Littlefield tells Fox News, "We didn't mess around. What we put on the table was unheard of. We went in there with a staggering sum and there was tremendous confidence that no one could walk away from it... (Seinfeld) came to me and said, 'I don't have a life, I'm not married, I don't have kids.' We gave it everything we had, he was tempted, but in the end it was a quality of life decision."

Seinfeld married his wife Jessica in 1998, the same year the show came to an end, and they have three children.
