During an interview on Ryan Seacrest's KIIS-FM radio show on Thursday, Jessica Simpson revealed that she's "done" having more children with her husband, Eric Johnson.

E! News reports the couple are already proud parents of 2-year-old daughter, Maxwell and 14-month old son Ace -- both of whom were unplanned pregnancies.

"Oh, we are done," Simpson said on the show.

She then quickly added to her statement.

"I say we're done," Simpson continued. "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 way that Simpson attempts to ensure no surprise pregnancies pop on her end is by turning down her husband for sex, she revealed.

"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 said.

Simpson also dispelled the rumor that she and Johnson have a daily morning champagne toast to their marriage.

"That is so not true," she told Seacrest. "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 and Johnson officially tied the knot on July 5 after four years of dating. Since then, Simpson revealed that she has changed her last name legally but continues to use Simpson on all other platforms.

"Jessica Johnson. Doesn't that sound like the best stripper name ever?" she said. "I did change it, but for everything else it stays the same. I guess I didn't change it on my Instagram or my Twitter, so does that not make it official?"

Simpson then went on to confess that she uses her famous last name to get into restaurants.

"It depends on what restaurant it is. If it's a hard restaurant to get into, I will definitely say 'Simpson.' It helps a little bit," she said. "My license says 'Jessica Johnson.' That makes it legit."
