Kids could be my back-up singers: Jennifer Lopez

London: Singer-actress Jennifer Lopez says her children love watching her perform and know her songs so well that they could be her backing singers.

The 43-year-old star says Max and Emme, her four-year-old twins with ex-husband Marc Anthony, could be back-up singers, reported Showbiz spy. "They watch the show almost every night - they love it, they`re excited by it. We were having lunch and I started singing `Cause I have spent all of my life` [from `Waiting for Tonight`], and at the same time both of them go, `Waiting for tonight, oh-oh`. It was hilarious. "I could employ them as back-up singers. They`d be cheaper," she said. Lopez, who is dating dancer Casper Smart, said she is at her happiest spending time at home with the children. "The best thing about being a mom is the love you feel and the joy they bring to you. I`m never happier or more complete than when I`m lying in bed with my babies, watching a movie." PTI
