Mario and Karina Deny the Breakup!

Karina Smirnoff has denied breaking up with boyfriend Mario Lopez, telling E's (and DWTS') correspondent Samantha Harris, "Mario and I are fine. Everything's good."

Mario also wrote in (via e-mail) to say "It's all good."

"It's all good"??? Doesn't sound like much of a denial to me!

And check out the video below, taken about a week and a half ago - when we asked Mario if everything was cool with Karina, his response, after a slight hesitation, was "I'm cool with everything all the time!"

Yeah, right!
