Silverman fell pregnant with Cowell's child last year following an on/off relationship and the news caused uproar as she was married to the star's friend, Andrew Silverman, at the time.The lovers became a couple once the divorce was finalised and they welcomed a son named Eric in February, and although he is proud of his child, The X Factor boss wishes he had behaved differently.He said: "I regret that part. But then of course you have a baby and you kind of go "This is what happened from it"."In this situation you are not going to come out of this well because of the circumstances. It's not something I am proud of or wanted to happen in terms of hurting anyone."It just happened. You have to deal with it and man up to it. You have to accept the responsibility and the criticism. All I can say is, my advice to you is if it happens to you, you just have to deal with it a day at a time and own up to your responsibilities."
