The happy couple of almost six years -- who tied the knot in July 2011 -- both turned one year older on November 9. (On Friday, Vanessa turned 32, while her hubby feted the big 3-9.)
This year, the duo has even more to celebrate than usual: on September 12, they became parents to son Camden John, their first child together.
Since then, Nick tweeted he's been "officially in cheesy dad mode." Vanessa, for her part, still can't quite believe their good fortune.
Explaining that motherhood so far has been "weird and very surreal," the Wipeout host told SheKnows.com that she's "still in shock."
"We look at him and we are like -- we made this!" she gushed. "I know it sounds corny and cheesy, but [your baby] is your love personified."
