Simon Cowell was every bit the doting father as he shared the first pictures of his new born son on Twitter.
The music moguls' girlfriend Lauren Silverman gave birth to a healthy baby boy on Valentines day. 17.45 EST on Friday, Valentine's Day, weighing 6lbs 7oz.
Cowell tweeted three black and white photos featuring himself, Silverman and Eric, telling his followers: "…now you can see how handsome little Eric is."
With a picture of him cradling Eric he said: "I never knew how much love and pride I would feel."
Returning to the New York hospital on Saturday, the 54-year-old music mogul was beaming with all the pride of a new father, as he gave a thumbs up to onlookers.
Dressed in his trademark baggy jeans, T-shirt and a heavy coat, he arrived brandishing a red bag, perhaps containing a gift for his new born son, who he earlier revealed would be named Eric after his father.
A source said: "Lauren's mother and sister were in the delivery room with them when she gave birth. Simon's mother, Julie, is looking forward to meeting the baby in the UK."

Speaking at the Mending Kids International All Star Concert for Children Worldwide In Los Angeles, he said: "So good luck to him and his partner and his new child. I think having a child is a responsibility.
"I had a child when I was 17-years-old and you can do both. You can have a family and still enjoy being in show business. It can be done but you have to make sure that you put your time in, and be a loving father that is all you have to do.'
