Vanessa, 35, and Nick Lachey, 42, both announced on Friday via Instagram that they are expecting their third child. The baby announcement -- which showcased Vanessa's growing baby bump -- also cleverly revealed that they are moving into another house.
Perhaps the new baby will be a fan of 98 Degrees, because Nick joked with ET earlier this year that his son is not a fan of his musical chops. "I sing around the house and my son tells me to stop!" he said with a laugh. "He says, 'Daddy, stop singing.' I go, 'Do you understand that people used to pay daddy -- and hopefully will again -- pay daddy to sing?' He has no clue. He has no concept."
