Is the world ready for Simon Jr.? Because Simon Cowell says he's having a son!  

The "X Factor" judge reveals to "Access Hollywood" that his girlfriend Lauren Silverman is carrying their baby boy. 

Cowell said he kind of knew it was going to be a boy but wouldn't have minded had it been a girl.  He also says he might call his son "Tad" because his first thought was tadpole when he first saw pictures of his unborn child. 

Simon also 'fessed up to getting very attached to the idea of fatherhood, telling "Access Hollywood's" Shaun Robinson that never wanted kids before but that he's the complete opposite now.
