Chris Hansen, best known for his “To Catch a Predator” series on “Dateline NBC,” has reportedly been caught by undercover cameras cheating on his wife with WPTV reporter Kristyn Caddell, who is 20 years his junior.

According to the National Enquirer, Hansen has been having an affair with Caddell for nearly four months.

Hansen lives in Connecticut with his wife and two sons but has been spending time in South Florida apparently working on a story about the disappearance of James Trindade, a local man who went missing back in 2006.

Hansen and Caddell were introduced in the VIP area of a West Palm Beach club and “there was an immediate physical attraction between them,” a source told the Enquirer.

“Chris and Kristyn got on so well that she ended up going back to his room at The Colony Hotel in Palm Beach–and later boasted to pals about staying the night with him,” the source says.

Tipped off about the alleged affair, the Enquirer set up a sting operation to prove that Hansen was maintaining a relationship with the young, blonde reporter. Last weekend, the tabloid recorded the two having a romantic dinner before spending the night together at Caddell’s apartment.

Calls and emails to Caddell were not immediately returned.
