Simon received the greatest gift for Valentine's Day, the birth of his first child, Eric Philip, with girlfriend Laura Silverman.

Cowell is mostly known for the unforgiving criticisms he gives to confident contestants as a judge on shows such as "The X Factor" and "American Idol."

"There's a lot of boring things that happen when you have a baby," said Cowell to HollywoodLife.com last November.

A source who wished to remain unidentified revealed people should not judge the British music and talent competition judge based on how he is portrayed on television.

"Simon is one of the nicest celebrities and one of the nicest people one would ever meet. His persona that you see on his shows is strictly for television. He is a genuinely nice and warm guy. And with this new chapter in his life starting, he can't wait to experience everything that comes with it. He is completely over the moon," said an anonymous insider to HollywoodLife.com.

Cowell's first child came with a bit of controversy due to a shocking affair with his friend Andrew Silverman's wife. The stunned husband instantly filed for divorce. Cowell reportedly does not want to hide any secrets from baby Eric regarding how his parents met.

"One thing Simon is straight up," said the unnamed insider to the HollywoodLife.com. "He will absolutely make sure that his son knows the history of him and his mother when he's at the right age, so he knows exactly the circumstances surrounding his existence."
