Jessica Simpson and her new husband Eric Johnson, who tied the knot back in July, are already proud parents to two children, daughter Maxwell (2), and son Ace (1), but being a mother of two seems to be enough for the 34 year-old singer.

Simpson recently revealed she is "done" having children with Johnson because neither of her two pregnancies were planned, but after making this comment she also realized this could happen again.

"Oh, we are done," Simpson said during Ryan Seacrest's KIIS-FM radio show Thursday (Sept 18th). "I say we're done. I don't want to accidentally get pregnant one day and then that poor kid feels like it wasn't meant to be or something. We've got the girl and we've got the boy."

One strategy Simpson has utilized in order to stop the surprise pregnancies is to frequently turn down her husband for sex. "After four years, there are definitely moments where you say, 'No.' It's not like rejecting Eric as a man-it's just that one moment. I'm like, 'Give me five minutes,'" she explained.

Even though their wedding was over two months ago, there are rumours that claim the newlyweds are still celebrating by having daily morning rituals of champagne toasts for breakfast, but these are obviously false.

"That is so not true," she said while laughing. "If anything, we wake up and I'm like, 'Stop breathing on me!'...We have felt like ever since we got married, we've been kind of living on this honeymoon, for some reason. Life is better. But we don't toast every morning with champagne."

Simpson first began dating Johnson around four years ago when they were introduced by a mutual friend, and they became engaged not long after in November 2010.
