You may like the idea of dating a lady who digs porn, but there can be serious repercussions, particularly if you're a dude who looks like a porn star.

Amanda Montoya was sitting down with her man to watch a little adult entertainment, and she somehow mistook him for the stud on the screen.

In a jealous rage, Montoya attacked her boyfriend with a knife. He was able to escape her clutches, fled the house, and tore down the street wearing only his shorts.

Now if this were actually in a porn movie, the point when the dude is running down the street almost naked is when the wah-wah guitar line kicks in.

However, as the victim explained, this was definitely not direct-to-DVD entertainment.

"She almost shanked me and everything. She put the (expletive) knife right under my throat," he told a 911 operator as he ran.

The victim, who claimed Montoya had already stabbed him in the face and bitten his chest, was able to corral a deputy at a local parking lot with the blade-wielding Montoya still hot in pursuit.

Montoya was arrested on a variety of charges, including child abuse, because she had charmingly left her eight-month-old son home alone to chase down her porn-star boyfriend who wasn't.
