A source close to Chigvintsev told ET on Wednesday that the reason for the breakup was "nothing dramatic."

"Torrey broke up with him about a month or two ago, and Artem is pretty bummed about it," the source said. "Torrey was over the relationship and the distance was a lot for them to handle. She has been in Chicago filming Chicago Med while Artem is in Los Angeles for Dancing. Distance was a main factor."

While it appears DeVitto has deleted almost all of her pics of her and her former beau on Instagram, Chigvintsev's account still features snaps of the two, the last being a selfie that was posted on March 6.

DeVitto, 32, and Chigvintsev, 34, started dating last May after mutual friends set them up on a blind date.

"It's all very brand new," a source close to DeVitto said at the time. "They're having fun."
