The couple wed in 2011 following Nick's divorce from first wife Jessica Simpson.

On Friday they announced their good news as they posted a sweet Instagram snap in front of their home with their children and dog.

'We got a new crib! Now we need a new crib!' was written on the image.

Vanessa was seen cradling her baby bump and another caption lower down read 'Newest Lachey arriving Spring 2017.'
