Dancing with the Stars pro Cheryl Burke has split with her model boyfriend, Maxwell Zagorski. Insiders tell PEOPLE the couple decided to call it quits because they could no longer handle being in a long distance relationship.

“This distance was so hard on the relationship. She lives in L.A. and he lives in New York. After a while it was just really hard for them to get together.”

Burke, 25, and Zagorski, 22, began dating last winter after being introduced by singer Lance Bass, who was partnered with Cheryl’s castmate Lacey on Season 6 7 of ABC’s reality ballroom competition. Cheryl is expected to return to the small screen when Dancing with the Stars begins its 10th season in March.
