According to People.com:
"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.

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. " (SOURCE: People.com)

Lopez is keeping himself occupied on the East coast these days, starring on Broadway in "A Chorus Line."

Yo might be wondering, who is Michael Yo?

He's a "Hollywood expert" according to, well, Michael Yo.
