Simon Cowell has broken his silence on reports he is to become a father, saying it is ''one of those things''.

The 53-year-old music mogul is allegedly expecting his first child with New York socialite Lauren Silverman - the estranged wife of his friend Andrew Silverman - and while he failed to deny the news, he vowed to remain silent on the details in order to protect ''a lot of people's feelings''.

Speaking at an 'X Factor' USA press conference at the Fox panel at the Television Critics Association meeting in Beverly Hills, he joked: ''I haven't read the newspapers. Am I missing something?''

He then added: ''There are a lot of things I will eventually clear up when the time is right. I really have to be sensitive here because there are a lot of people's feelings involved.''

Meanwhile, Andrew has filed for divorce from 36-year-old Lauren - who he has seven-year-old son Adam

with - and she is keen to end her relationship with him ''amicably''.

She said in an official statement: ''I am committed to sorting things out with Andrew as amicably as possible to ensure the well-being of our son. I would hope for some space and privacy in order to work through this.''

Her lawyers, Robert Cohen and Bernard Clair of Cohen Clair Lans Greifer & Thorpe LLP, added: ''We are working to resolve this situation in a fair and reasonable way that protects the best interests of our client and her son.''
