Jessica Simpson appeared on Monday's episode of Ellen, where she revealed that she and husband Eric Johnson are done having kids. "I'm not pregnant on your show!" Simpson joked, remarking that she's usually expecting when she appears on the talk show. "We got an IUD. Nothing is going to get into that uterus. I have two beautiful children and I'm not having a third. They're too cute! You can't top that." The 37-year-old Simpson and 38-year-old Johnson are parents to 5-year-old daughter Maxwell and 3-year-old son Ace. They tied the knot in 2014.
