"We have no idea. The doctor doesn't even know. It's a surprise!" she exclaimed to Us. "I'm the person who could have had three boys or three girls and not care. Also I was always into keeping the surprise, but at the end of the day I had a hard time. I think I have more will power this time!"
Kimberly and the Dawson's Creek alum, 36, tied the knot in August 2010 and already have daughter Olivia, 2, and son Joshua, 19 months. They announced in August they were expecting yet another little bundle of joy.
"Its nuts! I'm really busy," Kimberly told Us of the couple's busy household. "It's becoming easier because now they are becoming great friends," she said of her two children. "They definitely know how to argue, but they spend the majority of the time loving each other and laughing. When Joshua my youngest cries, my daughter Olivia will rub his back and tell him its okay. It's really sweet."
Kimberly also admitted that running around with Olivia and Joshua -- as fun as it may be -- isn't making this third pregnancy any easier! "It's harder being pregnant with two toddlers. I'm exhausted [with] this pregnancy! I'm really tired. Its tough to take a break. This is my most exhausting pregnancy yet."
Surprisingly, the redhead hasn't had any cravings yet, and couldn't even begin to guess whether she's having a boy or a girl. "This pregnancy feels very similar to both. I go back and forth. Olivia lately has said sister but all my friends think boy," she said.
But what about date night? Kimberly and the former Don't Trust the Bitch in Apartment 23 actor make sure to always keep the romance alive. "We make that a priority," she said of making time for each other. "A lot of times if he films late, we will go out and have dinner after and do something like that or we will go to a matinee on the weekend occasionally. We try to do something every few weeks."
Of course, Van Der Beek never forgets about bedtime stories either! "He is really a hands on dad!" Kimberly gushed. "He has an intense filming schedule, but he tries really hard to get home to put them to bed. Normally I will give them a bath and he will do storytime and bedtime." by Nivel
