The Little Couple. And now, mom gets to have a name in the house she's always wanted.
"When Jen and I met she started calling me Will," Klein tells
PEOPLE, laughing. "I said, 'My name is Bill,' but at least for a weekend
she called me Will until she finally gave up."
When the couple adopted their son William Rijin, they already knew what his name would be when they welcomed him home to Houston, Texas.
