Dancing with the Stars hostess Samantha Harris, 33, will be waltzing into motherhood with hubby Michael Hess.

Usmagazine.com catches up with the expecting couple backstage at Dancing, where they tell us hiding Harris’ baby bump wasn’t nearly as difficult as concealing her larger, um, milk ducts.

“Being on a very widely watched show makes it hard to hide any sort of physical changes. And so there was a lot of talk as to whether I had any enhancements done to my upper body,” Harris says.

Hess adds, “I had a lot of friends ask me. They were like dude!”

Harris says she didn’t tell her stylist until a few days ago, but those form-fitting dresses didn’t leave anything to the imagination.

“She said, ‘I have known for a while. I can’t look at you this closely on a daily basis and not know that you have these changes going on,’” Harris says. “So she was great. And it became a lot more flowy dresses and empire waists. And the one mistake I made was wearing a purple satin dress that was a little bit too tight, something you would not want to wear if you had a baby bump and had a quesadilla right before the show.”

The couple, who just bought their first home, has decided to let the baby’s gender be a surprise – so they painted the nursery periwinkle blue and will accessorize accordingly.

“We knew that it could go with some boy colors with chocolate or green, and it can go with the girl colors with some pinks,” Harris said.
