Jessica Simpson called in to On Air with Ryan Seacrest this morning, and not only did she chat about her fashion line, but she also gushed about married life and her family.

Jessica and hubby Eric Johnson have a daughter Maxwell, 2, and son Ace, 14 months, and when Ryan asked the singer if she was planning on having more kids, she said:
    Oh, we are done. 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."

But just because they're not having more children doesn't mean they're not uh, practicing. Ugh. We don't want to think about this! When Ellen K. pointed out that "there must not be many times" Jess can turn down her hunky hubby, Jess replied, "Oh my gosh, yes. 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.'"
