Speaking to Daybreak on Tuesday, he said: "I'm happy about it, I really am.
"It's nothing to hide now and the fact that I can now talk about it publicly is great."
The 53-year-old is expecting his first baby with New York socialite Lauren Silverman.
Cowell fell for the 36-year-old after her marriage to New York property mogul Andrew Silverman broke down.
The real estate developer had filed for divorce in early July, citing adultery for the split and naming Cowell as a co-respondent, but the matter was settled out of court.
Chatting alongside comedian Harry Hill, the pair were promoting the X Factor based musical 'I Can't Sing!'
"It takes the p*** out of me," said Cowell of the stage event which tells the story of a young woman who lives in a caravan and finds fame on an X Factor- style show.
He added: "We have had people approach us before about musicals, but they have always took it really seriously and I was like "Oh, forget it, I couldn't do that".
"But when they explained the premise and played me one of the songs, it really, really made me laugh and it captures what it's like to be on the show, what the contestant's back stories mean.
"And when they told me they got (Downton Abbey star) Nigel Harman (to play me), I was really happy because I think he is really funny.
"I am probably more excited about this opening than anything else I have ever done."
And Cowell playfully suggested that his newborn child would be present at the premiere of the musical.
"I timed it well," he joked.
