Simon Cowell says he still hasn't changed son's nappy

Simon Cowell called his newborn son Eric "little sweetheart" over Twitter, but the new dad admits he has never changed his son's nappy.

The 54-year-old 'X Factor' judge, who welcomed Eric with lover Lauren Silverman, told OK! Magazine that Eric's not a trouble baby, the Mirror reported.

Cowell added that Eric looks nothing like Silverman and has his mouth.
