Nick Lachey apparently has no regrets about not having children with his ex-wife Jessica Simpson.

In an interview with Jenny McCarthy on her Sirius XM show "Dirty, Sexy, Funny" on Wednesday, the former 98 Degrees singer admitted that he was grateful he never had children with Simpson, who he was married for three years and divorced in 2005,

"How happy are you that you didn't have a baby with Jessica?" McCarthy boldly asked the singer.

"I think in our situation, that was probably the best thing that could have ever happened is that we didn't have kids," he told McCarthy. "All things being equal, it was the best thing probably for the both of us that we went on with our lives and she's obviously happily married with two [kids]. I'm happy married about to have two so it all worked out the way it was supposed to work out."

Both Lachey and Simpson remarried and have children with their spouses. In July, Simpson married former football player Eric Johnson and the couple have two children together: 16-month-old Ace and 2-year-old Maxwell.

The 41-year-old "Big Morning Buzz" host and his current wife TV Personality Vanessa Lachey have 2-year-old son Camden and a little girl on the way, which the couple revealed in July by tweeting a photo of the words "it's a girl" written in the sand.

As for being friends with your ex's, Lachey said he and Simpson have not stayed in touch.

"She and I don't necessarily stay in each other's lives," he told McCarthy. "I wouldn't say it's friends and I wouldn't say it's enemies - there is just no contact. We both moved on with our lives...it's not animosity, it's not friendship, it's just kind of nothing."

With the topic of ex-spouses aside, McCarthy questioned Lachey about having sex with his pregnant wife.

"You get to this point, you've got to get very creative with your positioning," he shared. "[But], I'm not sure she's that comfortable right now with much of anything, including sex, it's been an uncomfortable time when you get into the last month and a half."

He added, "It was my birthday weekend this [past] weekend though, so I did howl at the moon a couple times."

Most of the time, Lachey said it about helping his wife stay calm, saying, "As a man, you also appreciate what your partner is going through and the transformation they're going through and all the stuff that comes with it. The least we could do is be agreeable."
