Extra host Mario Lopez visited The CW Twin Cities in May 2008 to promote his new book, "Knockout Fitness", and talk about life on the set of Extra. Along for the ride was Dancing With The Stars' Karina Smirnoff.

Okay, time to get serious people… we're on a schedule!

Karina and Mario look over scripts during lunch…

…and autograph some Extra gear for his fans.

Mario was all too happy to sign autographs and pose for pictures with The CW Twin Cities staff.
