Simon Cowell and Lauren Silverman left hospital with their baby son Eric yesterday (16.02.14), and are believed to be currently staying in a hotel.
The 54-year-old music mogul was seen carrying baby Eric - who was born on Friday (14.02.14) - in a car seat out of New York's Lenox Hill Hospital yesterday (16.02.14), and he, his son and girlfriend Lauren Silverman got into a waiting vehicle, which was believed to have taken them to a nearby hotel.
And the youngster has already settled in at home with his parents' beloved puppies Squiddly and Diddly.
Simon tweeted last night: "The last three days have been incredible. Eric Lauren sqiddly and diddly all happy.(sic)"
Though Eric is just a few days old, insiders say Simon is already a great dad.
One source told The Sun newspaper: "Eric is a lovely baby. He's very calm, sweet and very handsome.
"Simon's loving every minute and won't put little Eric down. He's taken to it like a natural and can't stop smiling."
The 'X Factor' boss has already shared a number of pictures of Eric on his twitter page.
Alongside a picture of himself cradling the little boy into his chest, he wrote: "I never knew how much love and pride I would feel."
And a photograph of himself, Lauren and the baby was captioned:"Mum, Dad and Eric. Now two days old."
Alongside a third picture, just of the baby, he wrote: "Now you can see how very handsome little Eric is."
Simon is expected to return to the UK later this week for the 'Britain's Got Talent' auditions.
