Simon Cowell and Lauren Silverman are expecting a baby boy together

The `X Factor` boss and his newly divorced pregnant girlfriend, who already has a seven-year-old son, Adam, with her ex-husband Andrew Silverman, are reportedly thrilled that they are set to welcome a little boy in February.

A source close to the couple told the New York Daily News` Confidential: "He is over the moon to be having a son."

Simon recently admitted he`s "not great" with babies even though he can`t wait to be a father.
He said: "I do like kids, I`m not sure I can deal with the whole baby thing, I`m not great with babies, but I`m good with kids, you know once they can talk to you and you can talk to them, I think it`ll be fantastic!"

The 53-year-old music mogul also confessed it was quite a shock when Lauren contacted him to say he was going to be a daddy.

He said: "It was a surprise initially ... I got a phone call with the news. Some of the circumstances around this were very uncomfortable to say the least, you know ... but it happened and she`s an incredible girl. Once I got used to the idea that I was going to be a dad, then I was really happy, really happy. So, I`m really looking forward to it ... It was quite dramatic, but you have to put things into perspective, it happened and I think I`ve dealt with it well. Overall I`m probably happier now that I`ve ever been."
