Jennifer Lopez only lets her children use iPads once a week. The 'American Idol' judge admits she is a strict parent to seven-year-old Max and Emme and introduced "Sunday Funday" as an incentive for her kids to be good during the week so they can enjoy electronic games at the weekend. Asked what a typical Sunday involves, she said: "It starts with a late breakfast. We sleep in, even the kids sleep in. And Sunday Funday, they work towards that because they don't get to use their iPads during the week. "Or play video games or anything because it's school time. And they have to be good in school and then they get Sunday Funday. It's something I made up so they could work towards it and behave!"
