Ex-WWE Star Victoria -- Husband Body Slams Gun-Toting Intruder

Scary moment for ex-WWE superstar Victoria ... when her husband confronted a gun-toting intruder at her Chicago restaurant ... AND BODY SLAMMED THE GUY.

We spoke with Victoria -- real name Lisa Marie Varon -- who tells us a suspicious man entered "The Squared Circle" restaurant this weekend and started making trouble inside the women's bathroom.

That's when Victoria's husband, Lee (who manages the joint) approached the man to find out what the hell he was up to.

According to Victoria, the man tried to push his way into the kitchen ... so Lee sprung into action and attempted to physically restrain him.

Lee says he saw the man reaching for his waistband and believed he had a gun -- so he slammed the guy down to the ground.

Turns out, Lee's instincts were right ... the guy did have a gun -- which was quickly recovered by one of the cooks.

Cops were called to the scene and arrested 18-year-old Arnez Harper on a count of felony aggravated unlawful use of a weapon.

"He (my husband) used to be a bouncer when he was a young lad," Victoria says of her hubby ... "I think that guy crossed the wrong person."
