As adamant defenders of all Saved By the Bell alumni - we seriously believed Dustin Diamond didn't release that sex tape! - we feel the need to call out Karina Smirnoff.

What are you doing, home girl?!?

The Dancing with the Stars professional accompanied the wrong Mario to Crustacean Beverly Hills Monday night. We have no idea where boyfriend Mario Lopez was as these two headed out after performing the paso doble in the ballroom.

But we do know this: AC Slater was All-City in four sports in high school and sang in the chorus. Don't mess with him, wanna be Mario!

Karina Smirnoff heads out on the town with a Mario whose last name is not Lopez.
