pros Maksim Chmerkovskiy and Peta Murgatroyd are great instructors in the ballroom, but they might have some learning to do about being a student in Lamaze class!

The couple got kicked out of their first birthing class on Saturday, according to a video Chmerkovskiy posted to his Instagram page, which features Murgatroyd laughing in the background as her fiance recounts how she “was misbehaving and not listening to anything.”

“That’s what happens,” the DWTS pro added with a laugh. “This baby’s gonna be a disaster.” 

“@petamurgatroyd was the worst student in class, but I don't blame her cause it was a million hours long and we've been shown waaaaaaaay too much stuff!” Chmerkovskiy explained further in the caption to his video. “My hair is indicative of the 'stuff' we've witnessed. #traumatized #NothingToHashtag.”

Later that night, the expectant parents stepped out for a Broadway date night to support fellow DWTS alum Mark Ballas in his run as crooner Frankie Valli in Jersey Boys.

“Couldn't be more proud of @markballas for his role in @jerseyboysbroadway!!!” Chmerkovskiy captioned a video from the audience. “Here's to many more standing ovations and sold out theaters!!!”

And, he made sure to note, “@petamurgatroyd did NOT get kicked out of this one ?.”

Chmerkovskiy and Murgatroyd announced that they were expecting their first child back in May after getting engaged last December. See more on their forthcoming bundle of joy in the video below!
