Appearing very happy, Cowell and his girlfriend, mom to Eric, born on Valentine's day, walked Yorkshire terriers Squiddly and Diddly by the shore, letting caregivers watch their ten-day-old son.
As Radar's photos show, the couple couldn't stop smiling as both held a dog's leash and looked color-coordinated as shirtless Cowell, 54, wore blue print boardshorts and Silverman, 36, was radiant in a blue maxi dress.
At one point, they leaned close together and touched shoulders. Later, Cowell walked one of the dogs near the surf while Silverman took a much-needed rest on a beach lounger with the other pooch.
The X Factor and former American Idol judge said proudly after Eric was born, "He's doing brilliant. I feel like a daddy."
And the latest photos prove everything is going swimmingly between him and Silverman, too!
