“Right now we’re figuring out what is going on,” Chmerkovskiy, 36, told reporters backstage after Monday’s episode of DWTS.
“For the longest time, [Peta] was, like, ‘The body parts are getting bigger!’ Or she would have morning sickness — we got lucky and she never really threw up, but she felt yucky — and she would say, ‘What’s wrong with me?’ ”
But Chmerkovskiy has done his best to calm his fiancée’s nerves.
“I would tell her, ‘We know exactly what it is. You’re pregnant and congratulations,’ ” he said.
