Five days after his split from Karina Smirnoff, Maksim Chmerkovskiy is already moving on.

"It's life," the Dancing With the Stars pro tells Entertainment Tonight. "You do your thing and then you move on."

How is Chmerkovskiy, 29, coping?

"Thank God for this season because all my attention goes to Debi [Mazar]," he says of his celebrity partner on the show's upcoming season. "This is probably the most serious I've ever taken a season. In light of everything that's happened, this is what I want to focus all my attention on."

The professional dancers got engaged on New Year's Eve 2008 -- six months after Smirnoff, 31, split from Mario Lopez. They planned to wed next summer.

Smirnoff said she wasn't surprised at the attention after they announced they called off their engagement.

"It comes with the territory, being on the show that has become amazingly successful," she told ET in a separate interview. "Everything is in the public eye, but again, it is a private matter. It is a private relationship, and it should totally stay private."
