Chip, 43, and Joanna, 40, tied the knot on May 31, 2003. They share four children -- Drake, 13, Ella, 11, Duke, 9, and Emmie Kay, 8 -- and are expecting their fifth child, a baby boy, this summer.
When ET caught up with Joanna last month in New York City, she gave us an update on how her pregnancy has been going, admitting she's been craving a lot of sugar lately.
"Anything a 5-year-old or younger would love is what I am craving right now, which is so weird!" she joked. "For Drake, [I craved] ice and lemons, so I always made Chip go to the gas station late at night to get the crunchy ice because we didn't have that in our fridge. With the boys, it was always something citrusy and right now, I am craving oranges and lemons. And then [with] the girls, [I wanted] salty. I normally don't crave citrus, but I have to have an orange every day now."
As for what the pair plan to name their baby? According to the couple, they're currently battling that out. Hear more in the video below.
