Mario Lopez and Dancing with the Stars pro dancer Karina Smirnoff have recently split, a source confirms to PEOPLE.

The couple, who met during Dancing’s third season, never publicly acknowledged their relationship despite the fact that the pair were living together in Lopez’s Los Angeles home. A source tells PEOPLE Smirnoff is moving out of Lopez’s digs.

Lopez’s personal rep, Lisa Perkins, says, “It’s my policy to not comment on my client’s personal life.”

Smirnoff, who is now competing on Dancing’s sixth season with R&B star Mario, has been spotted recently with E! Entertainment personality Michael Yo. The two were seen dancing and canoodling at a recent event at Hollywood eatery Beso.

Lopez, meanwhile, is starring in A Chorus Line on Broadway, and recently returned to the ballroom with 18 Chorus Line dancers to tape a synchronized number to air on Dancing’s 100th episode on May 6. He’s also about to embark on a national tour to promote his upcoming book, Mario Lopez’s Knockout Fitness.-people
