"Everybody keeps saying, 'What do you want for Christmas?' And I'm like, 'I want to be pregnant'," she said shortly after the couple tied the knot.
"I want babies, yep I do!" Kelly didn't have to wait until Christmas, however, and she announced that she was expecting in November.
Two months later Kelly and Brandon found out that their new arrival would be a girl, with the Texas-born star taking to Twitter once again to tell her fans the news.

"We just found out we're having a girl officially!" she posted. "I knew it! Only a girl could cause this much drama with all this vomiting ha!"
While baby River is Kelly's first child, she is also stepmother to Brandon's children from his previous marriage, Seth, six, and Savannah, 12.
"My kids love her," Brandon's ex-wife Melissa told People in October. "I couldn't ask for a better stepmother for my children."
