New Baby On The Way For Gwen Stefani and Gavin Rossdale

Aw...they are such a great family, and now the Stefani/Rossdale's are expanding their family tree!

Gavin Rossdale's father, Douglas, tells Usmagazine.com.

"Yes, they are!" he gushed to Us Magazine early Tuesday in a telephone interview. When asked if he's happy, he said, "Of course!"

Stefani, 38, and husband Gavin Rossdale, 42, have a 20-month-old son, Kingston.

Awww...I bet Kingston is going to make a great big brother!!
