Mia Khalifa was brought to tears after being slapped across her breasts by Thunder Rosa.

The former Porn Hub star got more than she bargained for when she experienced the world of women's wrestling.

The adult entertainer featured on an independent wrestling circuit following claims that women's wrestling was ‘embarrassing.’

Having initially featured on the Sabotage Wrestling's War of the Genders 2 show in Texas this weekend, Rosa gave her an introduction to the combat sport, reports the Mirror.

Rosa put her through her paces in the squared circle with a series of drills.

Khalifa eventually stomached the courage to take a slap across her chest, crumbling to the canvas in agony.

Khalifa, who now has a role as a sports journalist and presenter after giving up X-rated performances, played up to her heel persona by branding one rival, Joey Ryan, a ‘giant, hairy man-baby.’

Ryan’s main gimmick is that he has a powerful bionic penis - and she declined the chance to check it out in front of the small audience.

But her bodyguard was not so lucky, as he got flipped over and put on the canvas by Ryan’s finishing tool.

Khalifa has been in the news with wrestling fans when she spoke out on Ronda Rousey seemingly impending switch from UFC to WWE, insisting she had no respect for the sport.
