WATCH: Woman hired a porn star to see if her man would cheat!

A suspicious girlfriend went to EXTREME lengths to catch her boyfriend out.

In a video that was posted to YouTube channel To Catch a Cheater, the distrustful lady revealed she'd hired porn star Valerie White to see whether her man would betray her.

In the clip, Valerie tells the unidentified male she is “lost” and asks for his number, but he replies: “What do you want my number for?”

Finally, he gives her the adult entertainer his number but also admits he has a girlfriend, suggesting: “We could hang out the three of us or four of us."

When Valerie hints at having a threesome with him, he tries to walk away, but she then asks him to drive her home.

“Is it cool if I stay with you? Just for the night?” she persists.

But then he gets suspicious.

“Why are you interested in me?” he asks, before she admits she’s a porn star, to which he runs away,

The man’s girlfriend, who is watching the events unfold on camera, appears relieved although she admits she feels “crazy” and has “mixed feelings” about her man giving out his number, but says that she will “stay with him.”

However, things massively backfire for her.

When she comes clean, her boyfriend is understandably upset about being set up.

“I’m done,” he says, dumping her on the spot.

Bet she wishes she didn't try to honeytrap him with a porn star now....
