SPOTTED: 90s television sitcom favorite and current host of Extra TV, Mario Lopez, and everyone’s beloved next door neighbor, Andrea Barber, hitting the neon-lit Las Vegas Strip at night with more than 35,000 runners to conquer the sold out Rock ‘n’ Roll Las Vegas Marathon & Half Marathon benefiting the Crohn’s and Colitis Foundation of America. Grammy winners Macklemore & Ryan Lewis started the night by performing their hits “Thrift Shop” and “White Walls”. Of course the event would not be complete without a rendition of “Can’t Hold Us” which is a perfect tune for the runners with lyrics such as “this is the moment, tonight is the night, we’ll fight ’til it’s over”.

Even with an injured rotator cuff, Mario Lopez rocked the Zappos.com Rock ‘n’ Roll 1/2 of the 1/2 and finished with fans who ran over to take selfies with the TV host after their memorable run. Mario was most excited to run RNR Las Vegas because he loves to run at night and what better place to do it then on the Las Vegas Strip! Favorite artist on his running playlist: Avicii.

Mario Lopez chatted with Meb Keflezighi (paced the 1:45 half marathon group) about his Boston Marathon win and telling him how big of a fan he was of Meb
