Benjamin is expected in three weeks.
The couple revealed in May that they were pregnant with a child. The pregnancy comes just one year after the death of their son Jett.
In a statement released by the couple they said "It's impossible to keep a secret... especially one as wonderful as this...We want to be the first to share this great news with everyone that we are expecting a new addition to our family."
The couple also have a ten year old daughter, Ella Bleu.
