Before
Dancing With the Stars, Mario Lopez was still best known for playing the character Slater on the 80s sitcom
Saved By the Bell. Now thanks to his impressive run on
Dancing With the Stars -- and a much-talked-about romance with his dance partner
Karina Smirnoff -- Mario is popular again. He is now the host of MTV's hit shows
America's Next Dance Crew and
Top Pop Group. He was also promoted from correspondent to host of the entertainment news show
Extra.
