Furious girlfriend attacks boyfriend after he tells another woman she’s his SISTER – but is it all a wind up?

A GIRLFRIEND exploded at her rogue boyfriend after he told another girl she was his SISTER and that he'd been single for two years before giving her a sexy massage.

Patrick was duped into thinking he was being interviewed to take part in a game show, but actually he was set up as part of a  stunt.

His other half watched on as he shamelessly flirted with the hostess, Veronica, between takes, rubbing her legs as she was "cold".

He then boldly asked her for her Instagram and promised to like her pictures.

She played along, encouraging him to touch her thighs and show her his tattoos, while his girlfriend appeared to look outraged from behind the scenes.

When Sam - the man behind the stunt - tried to appease her by pointing out Veronica was told to flirt with Patrick, she snapped: "It doesn't mean he has to fall for it. He's such a "f*****g moron".

Patrick was clearly trying to impress his newfound friend, telling her he loved his job and was a good cook.

Asked if he could give her a back massage he eagerly agreed, to which his girlfriend exclaimed: "I think this is cheating at this point, he's already touching her, he thinks the cameras are off, he's given her his Instagram, told her I'm his sister."

As Patrick got stuck into Veronica's shoulders, agreeing to "pick this up later", his girlfriend came storming over and gave him a piece of her mind.

She wailed: "I'm your sister?! You swapped Instagrams with her, you're putting your hands all over her," while Veronica acted innocent.

Patrick tried to dig himself out of it, explaining he was merely "at an audition for a game show", but his girlfriend wasn't having any of it.

She revealed she'd set everything up to see if he'd be a "f*****g cheater".

Remarkably Patrick tried to make out his partner was "tripping" and "embarrassing herself" - even after Sam told him he'd been set up.

His girlfriend ranted: "All the crap that I've done for you, you've been living in my f*****g house.

"Oh and hear it guys, he doesn't have a f*****g job! You don't have a job, how do you eat? Me!"

But Patrick seems more put out that he isn't "getting the part" on the game show.

Having been dumped by his girlfriend, Patrick then appears to try his luck again with Veronica.

Despite having been rejected by both women, he seemed more upset that he "didn't get the part".

Last year we reported how a woman hired a porn star to see if her boyfriend would cheat… and it ended pretty badly.

In January we told how a man found out his wife was cheating on him in the most savage texts ever - and his revenge was even more brutal.
