Karina Smirnoff & Maksim Chmerkovskiy: It's Over

We are sad to report that the smoldering Dancing with the Stars duo, Karina Smirnoff and Maksim Chmerkovskiy, have just called off their engagement.

"I am confirming that they did indeed break up," Karina's rep told E! News.

Word of the split comes just a month after they debuted on Broadway in Burn the Floor. Perhaps it was their busy schedule that contributed to the split.

That Broadway performance, in addition to the upcoming Season 9 of Dancing with the Stars, had already pushed back their nuptials until next summer.

"We don't plan," Maksim Chmerkovskiy said this summer.

"We're [rehearsing] 14 hours a day."

Karina and Maks will no longer be dancing the horizontal mambo.

"The only thing we've decided on is next year in June," Karina said. "We were supposed to pick the place, but we've never actually had the time to go further."

"We don't feel like we're messing out on the wedding dress fittings," she continued. "As long as we're together, tying the knot is a plus. It's something extra."

Or it was, anyway.

Will their breakup cause tension on the Dancing with the Stars set? What's the over-under on how long it takes before Karina reunites with Mario Lopez?
