The X Factor boss, who is expecting his first child with the New York socialite, became headline news back in July when the baby story first broke amid claims he had been named in Silverman's divorce papers by her now ex-husband Andrew.
Cowell admits the situation was "kind of uncomfortable" at first but has since calmed down, and he is adamant Silverman was treated unfairly after the news emerged.
He tells US talk show host Ellen DeGeneres: "It was kind of uncomfortable, you know, the situation. But these things happen and everything is kind of calm now and I'm happy. I'm actually happier than I've ever been...
"I obviously can't blame the media - it was kind of what I call a juicy story. But there was a lot of stuff that was said about her: that she trapped me and that she's a gold-digger. It's absolute nonsense. She's a great girl but, like I said, it was awkward because of the circumstances."
Cowell is rumoured to be in a relationship with Silverman after they were spotted kissing while on holiday together.
The interview with DeGeneres airs in America on Tuesday.
