The 28-year-old former 'Girls Next Door' star and her husband already have three-year-old son Hank IV together and after a romantic trip away together recently, they decided to expand their family, reported OK magazine.
"I want baby number two. We really connected and had the most romantic time on a trip to celebrate my 28th birthday last month. That's when we actually started talking baby. We're starting to try shortly," Wilkinson said.
Wilkinson said she doesn't care whether the couple have a son or a daughter as long as the baby is healthy and happy.
"Parenting has the power to bring a couple closer. You realise you're the only two people raising this amazing child, so you have to work together. It also makes you appreciate time together as a couple, because along time is harder to come by," she said.
