LOS ANGELES, California (X17online) - Actor Mario Lopez and professional dancer Karina Smirnoff have split up, a source tells X17.

Lopez, 34, and Smirnoff, 30, met on the third season of Dancing With The Stars, and were living together at Lopez's Los Angeles home until Smirnoff decided to move out.

X17 can reveal exclusively that it was Smirnoff who broke off the relationship when she began to suspect that Mario had developed a wandering eye.

A source tells X17 that Smirnoff was upset after seeing a picture of Lopez flirting with a Hooters waitress, but the last straw came when she learned that Mario was partying in New York City last weekend with Dancing With the Stars judge Carrie-Ann Inaba.

Lopez is currently starring in A Chorus Line on Broadway, while Smirnoff is competing on the sixth season of Dancing With The Stars.
