"Both Karl and I have grown up with German Shepherds and can't wait to welcome our newest member of the family, Chance the Yapper."
On Wednesday's Today Show, Karl also opened up about the new addition.
"I wasn't going to [get another dog] because I had a bit of an emotional experience when I was a kid," he explained.
"We had this German Shepherd for 15 years, Rocky, and he passed away and it was very said. I vowed that I would never ever get another dog.
"It's a big responsibility and I'm worrying about the emotions tied up with that," he added.
Congratulations to the pair!
