The X Factor judge and his girlfriend, Lauren Silverman, became parents to little Eric after she gave birth in New York on Valentine’s Day.
“Very happy to say Eric was born … Healthy and handsome,” Cowell wrote on Twitter. “Lauren in great shape. Thanks for all of your kind messages. Named after my dad.”
On Sunday, he also shared a photo of the little one. “I never knew how much love and pride I would feel,” he tweeted.
Eric is the first child for Simon Cowell and the second for Lauren, 37. She is already a mother to 7-year-old Adam from her marriage to Andrew Silverman.
