"'I like to waddle, you like to waddle. I like fish, and you like fish. You like to swim, and I like to swim. I like to walk in your footsteps standing tall like you. You have webbed feet, and I have webbed feet… and I will always love you, Eric.'

"It's my favourite thing I've ever had."

Cowell shares Eric with girlfriend Lauren Silverman, who gave birth to their son on 14 February 2014.
