and Hank Baskett are celebrating four years of happy marriage by trying to expand their family
with baby No. 2.
A recent vacation to Southern California's Big Bear Lake helped the couple further solidify their relationship, Wilkinson, 28, told PEOPLE on Saturday, as she hung out at a poolside cabana at Drai's in Hollywood's W Hotel to promote VEET hair removal products.
"Our week vacation in Big Bear, we found this new energy with each other, a new love
, a new fascination about each other," she said. "And right now, we found the key to happiness. We have the key to marriage, we have the key to parenting, why not right now bring a new life into this world while we're this happy? It just makes sense."
Wilkinson, who left the show Splash
last April and whose new season of Kendra On Top
premieres on WeTV later this summer, says she she'll explain the key to her solid marriage on new episodes of her reality show.
To prep for another run at motherhood, Wilkinson got her partying out of her system, taking trips to Miami and Las Vegas before deciding the time was right to give Hank IV, now 3½
, a new sibling.
Her husband, she said, is planning a surprise for their 4-year anniversary celebration, but she doesn't know where. Hawaii, she adds, is likely in their plans, but this time with their son along for the trip.
"I'm ready," Wilkinson says about having a second child. "I couldn't be more ready, and Hank couldn't be more ready. Our souls have connected, even Little Hank's. Little Hank keeps saying to us, 'I want a brother and a sister.' So we have included him in our decision, too."
