The singer-and-actress, who is married to Marc Anthony, added that the twins are the most important thing in her life, reports Contactmusic.
She explained: "When Marc and I are out we get out our phones and show everyone pictures of our kids. We probably do that a little too much. You always think you are not going to be that person - but then you are. We are just normal I guess."
She said: "Our babies are our priority, they are just everything and they come first. They just make everything better."
