The proud daddy, 54, and his partner Lauren Silverman, 37, took their baby son to lunch with them on Easter Sunday (20 April) and naturally it was nothing but the best for the privileged boy - at The Ivy in Beverly Hills, California!
In pictures of the family leaving the restaurant after lunch with friends, Simon can be seen cradling his son Eric and smiling happily at well-wishers.
Lauren looks rested and relaxed - a far cry from the usual dishevelled look of a new mum!
Simon and Lauren's lunch companions included his ex-girlfriend Terri Seymour who was seen cooing over the newborn.
Eric, named after Simon's late father, was born on Valentine's Day and has turned Simon into a gooey slushy father.
The Britain's Got Talent judge has said: "I never knew how much love and pride I would feel.
"I was born to be a dad."
He has also hinted that he'd like more children... Watch this space!
