Mario Lopez, a self-confessed fitness fanatic,  was recently spotted working out in Miami, swimming and jogging.  The 'Extra' host seemed unfazed after being SLAMMED on 'The Wendy Williams Show' by his ex-wife. Last week his ex wife former Miss USA Ali Landry called Lopez a 'liar and a cheater' on the popular syndicated talk show.
'I had heard something right before the wedding. [Mario] swore that it was not true, but I had that feeling in my gut, ' she said
'All of my family was flying in – it was a destination wedding – and I really should have put the brakes on it at that point, but I was afraid.'

'I confronted him and he still – to this day – denied it and never apologized. It was horrible.
The two tied the knot on April 24, 2004 in front of 50 guests outside Puerto Vallarta, Mexico and annulled the marriage two weeks later.

Whether he is a cheat or a liar, he definitely doesn't cheat his body when it comes to his work-out regime.
