Talk about uncomfortable situations!
"It's going to be kind of awkward to work with them, because we all have to be in the same environment and very often in the same room or even sitting next to each other on the same couch," Sliwinska told us this week when she and her celeb partner, Ashley Hamilton, stopped by the 9Planet Universe event in Los Angeles.
"It'll be awkward because I'm friends with both of them."
In fact, Sliwinska saw Chmerkovskiy just the other day…
"He just told us what happened and it's hard," she said. "It's a very difficult experience for the two of them."
Sliwinska said she didn't know what went wrong, but explained that two dancers in a relationship can be problematic.
"I can tell you from my experience that to be with a person you dance with is probably the hardest thing ever," she explained. "It takes a lot of patience. Imagine working with your husband. It's really tough."
Sliwinska and Hamilton, meanwhile, are getting along quite nicely. "We have a brother and sister kind of relationship," Sliwinska said.
