Vanessa Lachey Pregnancy

Vanessa Lachey Pregnancy, Every mother has her superstitions, but Vanessa Lachey’s might be a little zanier than most.The first-time mother sat down with Bethenny Frankel on the “Real Housewives” star’s new talk show, “Bethenny,” to share her biggest preganancy fear in an episode airing Friday.

“Everyone’s belly button is different,” she began. “Some women’s belly buttons pop and some women’s (don’t). I thought, ‘Oh, I wouldn’t mind if it popped because then it would be like the turkey’s done, right?’ And it’s cute.

“But my stylist was like, ‘You don’t want that to pop. That’s like having a third nipple.’”

The 31-year-old TV show host explained that ever since her stylist pointed that out, she’s become extremely paranoid about making sure she doesn’t pop her belly button out of her baby bump.

“Every time I sneeze, I hold my belly button in,” she laughed. “For some reason, I think I’m going to sneeze it out.”

Lachey and husband of one year Nick Lachey, 38, are expecting a baby boy this coming September. (New York Daily News)
