Uber-jock, A.C. Slater was Zack's main 'frenemy' and played by Mario Lopez. Slater would alternate between roles as Zack's co-conspirator and his competition for Kelly's affections. Following 'Saved by the Bell' Lopez appeared on the television series 'Pacific Blue.'
Lopez's real way back into the limelight was ABC's 'Dancing With The Stars' when he and Karina Smirnoff finished second to former Dallas Cowboys star Emmitt Smith and his professional partner, Cheryl Burke. Following his gig on 'DWTS,' Lopez went on to appear and host a variety of shows including 'Entertainment Tonight,' 'Ellen: The Ellen DeGeneres Show,' 'Live with Regis and Kelly,' and 'The Wendy Williams Show.'
Today, Lopez is the host of 'Extra' and 'The Sing Off.' He married Ali Landry on April 24, 2004 and got annulled less than a month later. Lopez's current girlfriend, Courtney Mazza, gave birth to a girl, Gia Francesca Lopez on Sept. 11, 2010 in Burbank, Calif.
