Simon Cowell has officially gone soft. The 54-year-old shared a series of adorable photos of his nearly 3-month-old baby boy Eric via Twitter on Monday, May 5.

The first photo the proud dad shared was a pic of baby Eric resting comfortably on Cowell's knees and gazing up at him. Cowell then shared a second pic, this time of Eric supporting himself and climbing over a couch. The British TV personality displayed his usual humor, captioning the pic: "Very handsome like his dad."

In a third photo, Cowell included Eric's "mum" and his girlfriend, Lauren Silverman. Silverman, 36, looks lovingly down at her baby boy while wearing large sunglasses.

Cowell surprised the world after the arrival of his first child when he gushed in an Extra interview: "I was born to be a dad!"

Us Weekly was first to break the news that Silverman and Cowell were expecting while she was still married to Cowell's friend, Andrew Silverman, back in July 2013.

In a recent interview, Cowell's ex-girlfriend Terri Seymour told Us Weekly the Brit is "really good" at being a father and "loves it." In fact, Seymour says he's a "natural!"
