Topless Mario Lopez To Rehash Day's Celebrity News For Floundering 'Extra' Mario Lopez, the dimple-cheeked actor who first rose to prominence playing the deeply conflicted Albert Clifford 'A.C.' Slater on the Chekhovian scholastics drama Saved by the Bell , has been announced as the new host of Extra . As we mentioned yesterday , ratings were declining steadily for the syndicated celebrity newsbite service; Warner Bros. was therefore looking to drop its current hosts (Mark McGrath, former lead singer of the Afro-Caribbean-flavored pop outfit Sugar Ray, and Dayna Devon, who apparently is not Nancy O'Dell) in favor of something fresher, absier, and more Eva Longoria-accessible . Weekend co-host Lopez fit that bill: "'He will be a fresh and dynamic presence, and we can't wait for him to assume his new role,' said senior exec producer Lisa Gregorish-Dempsey." Look for new features like the VitaminWater presents Extra's Live! From the DKNY Beach House!, and the Mario Lopez's Knockout Fitness Gym Couture Fashion Report.
