Simon Cowell Is a Dad!

There's a new idol in Simon Cowell's life: his son.

On Friday at 5:45 p.m., his girlfriend, Lauren Silverman, gave birth to a healthy baby boy at Lenox Hill Hospital in New York City, his rep confirmed to People. The new arrival weighed 6 lbs., 7 oz.

Though Cowell had been in London filming the audition stage of "Britain's Got Talent," the 54-year-old mogul made the 8-hour flight (reportedly by private jet) to be by Silverman's side. See? He's softening up already.

It has been a … let's call it … untraditional path to parenthood for this couple, who first revealed Silverman's pregnancy last summer, while she was still married to Cowell's friend, real estate tycoon Andrew Silverman. Since then, however, Lauren finalized her divorce from Andrew, went to Barbados with Simon, and enjoyed a glamorous baby shower (complete with a toast from the father-to-be). There have also been rumors that Cowell is gearing up to propose, but we're not going to count on that just yet.

While this is Simon's first spin at being a parent, Lauren already has a nearly 8-year-old son named Adam (from her marriage to Andrew). We guess that means it's Cowell who has some learning to do. Hopefully he's got talent when it comes to fatherhood.
