A porn star is facing more than 15 years in prison after she was arrested in Las Vegas for allegedly stabbing her boyfriend in the leg with a butter knife when she caught him sleeping with another woman.

Bridget Powers, who has dwarfism and whose real name is Cheryl Murphy, was taken into custody in Nevada last month after a neighbor reported hearing screams in the incident where she was filmed smashing a window with a barbecue grill.

Murphy, 39, was charged with burglary while in possession of a deadly weapon, and now she faces two to 15 years for that charge alone after prosecutors claimed that when she entered the home she had the intention of committing a crime, TMZ reports.

The woman - who goes by the name Bridget the Midget - also faces five years for battery with use of a deadly weapon constituting domestic violence, and six years for assault with a deadly weapon.

Bridget Powers - who goes by the name Bridget the Midget - allegedly stabbed Jesse James in the leg at his home in Las Vegas, Nevada September 18

In a video obtained by TMZ, the adult film star is heard yelling from outside the building after another woman reportedly picked her up and threw her out: 'I have nothing more to lose Jesse. You took it all from me!'

Later the video from September 18 appears to show the other woman emerge from the door and refer to 'my boyfriend'.

'There's blood everywhere, please call the cops!' she yells, as a group of men respond. 'You are the cops? Thank god,' she says before letting them inside.

Murphy, who is 3ft 9in, is then seen walking through the parking lot with a law enforcement officer.

KTNV reported that Murphy told cops who responded around 2.31am: 'It's my fault, I did it all. I should go to jail.'

The station reports that when asked if she lived at the residence Murphy responded that she did but another woman yelled back: 'No, she does not, she's trying to stab my boyfriend to death, please call the cops.'

Murphy reportedly added: 'Yeah, I did stab him.'

At the time of the incident Murphy reportedly told cops she lived at the home but another woman denied that she did

The other woman claims that Murphy tried to stab her too but missed.

The victim, Jesse James, was rushed to hospital with non-deadly injuries and has since been released from UMC Trauma.

The man told cops he had been out drinking with the other woman and they returned home to sleep. He woke up after Murphy entered through an unlocked door and stabbed him in the leg as he slept.

The man claimed he had been sleeping with Murphy for the past two years.

Murphy's court date was set for September 26.

On Facebook September 30, Murphy changed her status to 'in a complicated relationship'. In the same status she commented that she lived one block away from Jesse.

Asked if she stabbed the man, known as 'King Yea Yea,' she told one commenter, 'Ask Jesse.'

Jesse's status states that he is single.

A preliminary hearing was scheduled for November 7.
