For a guy that made a living catching people out misbehaving on camera you'd think he might of been a little more discreet when it came to his own life.

But, RadarOnline.com can reveal that To Catch A Predator host, Chris Hansen, has been caught cheating on his long suffering wife a SECOND time.

The National Enquirer are reporting that the 51-year-old married father of two embarked on a steamy six month affair with Kathleen Collins, a stripper that he met in Las Vegas in early 2011.
