Did your eyebrows go up a little when Maksim Chmerkovskiy gave Karina Smirnoff a greeting kiss on the cheek at the start of their rehearsal package on Dancing With the Stars Season 16 Week 5? It looked innocent enough, but pro dancers Maks and Karina were once engaged, and their split was apparently bad enough that Maks once said he would never speak to "that person" again.

But he said that in 2011 and this is 2013. As Maks’s brother Val already told Xfinity, it was a “terrible breakup” but it's all water under the bridge. And Maks and Anna Trebunskaya ended up being great additions to Karina's dance with Jacoby Jones.

Karina talked to People about working with her ex. "It was drama-less and so refreshing. I enjoyed it. I really did." However, she admitted, "It was a little awkward in the beginning, but once we started, it was great." Now their relationship is more civil. "It's back to where it should be – professional and fun. We're wearing heels, rhinestones and spandex. Let's put everything into perspective."

Maks and Karina were friends for a long time before becoming romantic, so maybe they can get back to where they were before whatever went wrong. But ... what about Peta Murgatroyd? Does Maks's more recent ex feel the same way? This is what happens when you mix business with pleasure — it’s hard to really move on!
