The singer/actress became a mum to twins Max and Emme in February 2008, and recent rumours suggested the couple was looking to add to its brood by adopting.
But Lopez has now spoken out to deny the claims - and she's adamant a brother or sister for her twins is not likely to arrive any time soon.
Asked about the adoption rumours, she tells Britain's Fabulous magazine, "No, no. That's not true. I would like to have another baby myself, actually. If it happens I'll be thrilled. But we're not trying."
