Leave it to Jenny McCarthy to ask the tough questions!

During an interview with Nick Lachey on her SiriusXM show, "Dirty, Sexy, Funny," the host came right out and asked, "How happy are you that you didn't have a baby with Jessica [Simpson]?"

Nick, who was married to the singer for three years before their split in 2005, replied, "In our situation, that was probably the best thing that could have ever happened that we didn't have kids."

The guy makes a valid point, considering it's much harder to go through a divorce when kids are involved. "You're always going to love your kids no matter how you feel about their other parent, but all things being equal, it was the best thing probably for both of us that we went on with our lives," he continued.

"She's obviously happily married with two and I'm happily married and about to have two so it all worked out the way it was kind of meant to work out."

Jessica married former NFL player Eric Johnson in July of this year and they have two kids together — Maxwell, 2, and Ace, 16 months. Nick married Vanessa Lachey (nee Minnillo) in 2011 and they have a two-year-old son, Camden, and a baby girl on the way.

When asked whether the ex-flames keep in touch, Nick responded, "She and I don't necessarily stay in each other's lives. I wouldn't say it's friends and I wouldn't say it's enemies — there is just no contact."

But he doesn't go so far as to hiss at Jessica when she comes on television, like Jenny suggested. "I don't rush right down to Macy's and buy a bunch of clothes or shoes, but I also don't hiss at the TV — it's somewhere in the middle," he joked of the successful fashion designer.

Jenny also managed to sneak in a few questions about the former boy bander's current sex life, given his wife is heavily pregnant.

"You get to this point, you've got to get very creative with your positioning," Nick said with a laugh. "It was my birthday weekend this [past] weekend though, so I did howl at the moon a couple times."

NOOOO! WE CAN'T UNHEAR THAT. It's up there with "Is this chicken…or is this fish?"
