Mario Lopez, host of ‘America’s Best Dance Crew,’ talks about MTV’s new show

Talented and dimpled, Mario Lopez first came to our attention on “Saved by the Bell.” He has since expanded his range in television and films and with an ever-growing array of hosting gigs, including the 2009 Miss America Pageant and the syndicated TV entertainment news show “Extra.” A runner-up on the third season of “Dancing With the Stars,” he also wrote “Knockout Fitness” about how to stay in shape. Last year, Lopez, 35, made his Broadway debut in “A Chorus Line.” He will be hosting the premiere of MTV’s “America’s Best Dance Crew,” at 9 p.m. Sunday.
