Man accuses girlfriend of lying about pregnancy on YouTube game show

A man has accused his girlfriend of lying about her pregnancy on a YouTube game show.

The Los Angeles man - known only as Jamal - appeared on an episode of To Catch A Cheater, a popular web series which has over 2.8 million subscribers.

Hosted by Luis Mercado, the episode begins with Jamal watching footage of a set up where the men have arranged for an actor to hit on his girlfriend, Zahara.

The aim is to see whether she cheats or not, as Jamal says that he is looking for a way out of the relationship after she recently told him that she was two weeks pregnant.

"I'm kind of hoping she falls for this guy who hopefully does a good job of trying to hit on her," he says, only to be disappointed when she turns down the man's advances on the street.

"I have a boyfriend and he really really really loves me and I really really really love him," Zahara says.

Frustrated that she didn't fall for the trap, Jamal says: "I need some help to get out of this that did not help me not one bit."

The next step is an extreme one, with Zahara arriving at a Compton residence under the pretence of participating in an online couples game show to win money with Jamal.

She's hooked up to a lie detector test, where a retired detective named Holden who claims to have worked with the CIA for 30 years runs her through a series of questions.

At the end of the interview, the pair are sat down together to go through the results.

After establishing a baseline for "truthful" answers by asking her name and shirt colour, Holden reveals that her response to questions about whether she has ever cheated on Jamal is "100 per cent not honest".

It only gets worse from there, with the former detective saying that her response to the question about whether she was pregnant was also "not truthful".

"Why would I lie about that?" she asks, questioning Jamal who gets up from the position on the couch they were sharing together.

Asking to do the test again, Jamal accuses her of lying about her pregnancy and the couple have a fight in front of the camera.

Zahara — who insists she is telling the truth — storms out of the house, only for Jamal to reveal to viewers at the end of the video that the couple have not spoken since.
