Simon Cowell and his girlfriend Lauren Silverman are being kept on their toes by 13-month-old Eric as he has learned how to walk and nowhere in their house is safe.
Ella Henderson - who is signed to Simon's record label Syco - said: "I saw Simon at the Brits and he was telling me how he can't control him, apparently he's walking and they've got baby gates everywhere."
As well as sharing his home with Lauren and Eric, Simon also has two Yorkshire terriers, Squiddly and Diddly, and Ella suggested the dogs are equally hard to keep in check.
Speaking to heat radio's Sarah Powell, she said: "When I went over to his house they both just come and sit and one sits on your shoulder and one sits on your head, if you sit on the sofa. They just run everywhere on you but they are really cute."
