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 the syndicated entertainment news show 'Extra' and 'The X Factor' on FOX. 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. The couple welcomed second child, a son named Dominic, in September 2013.
