Maksim Chmerkovskiy's starring role on the first Ukrainian edition of The Bachelor apparently wasn't as enjoyable as the Dancing with the Stars dancer had hoped.

"[It was] the hardest thing that I've ever done. If I knew then what I know now, I would never have signed up. I would do Dancing with the Stars for the rest of my life before I do something like this ever again," Chmerkovskiy told People.

Chmerkovskiy -- who previously claimed he had turned down an offer to star in ABC's edition of The Bachelor before a later report alleged his claim was untrue -- said he'd had no idea that the show's elimination format would be so emotionally distressing.

"I had never seen it, but I still knew what it was about. In theory you think you can do it, but when you're in it you cannot realize how difficult it is," Chmerkovskiy said.

In fact, Chmerkovskiy told People that he now disagrees with the reality dating show's core premise, which requires its star to compare bachelorette suitors against each other in order to determine who was the best fit for him.

"The fact that I had to choose people was something else. People should never be lined up and chosen. We're not objects and we're not supposed to be lined up like that. It's terrible and it's like I was back in high school," Chmerkovskiy explained.
