Britain's Got Talent judge Simon took Eric to The Ivy in Los Angeles and was snapped holding him in his arms outside once the meal was over.
Choosing to shun a baby car seat to carry his boy, Simon held Eric in his arms as he waited for his Rolls Royce to be brought round to the front of the restaurant.
Simon had wrapped Eric in a soft cream blanket to keep him warm and managed to multi-task by also checking his phone!
This isn't the first time Eric has been treated to a trip to the exclusive West Hollywood eatery.
Earlier this month, Simon was pictured carrying Eric following another posh lunch at The Ivy. Start 'em young, eh Simon?!
Simon became a dad for the first time after his girlfriend Lauren Silverman gave birth on 14 February.
The music mogul has since thrown himself into fatherhood and is clearly besotted with his little man. Aww!
