*YOUTUBER* KILLS BOYFRIEND IN STUNT

Washington : A YouTube prankster from US state of Minnesota has admitted fatally shooting her boyfriend in a botched video stunt she hoped would go viral.

Monaliza Perez, a 20-year-old mother of two, believed her boyfriend would be shielded by thick book as she took aim from a close range in front of the onlookers.

She pleaded guilty to second degree manslaughter last week and agreed serve a six month sentence.

Perez and Ruiz, 22, were recording the stunt in June for their YouTube channel, where they published videos of their daily lives and pranks they performed.

Ruiz convinced Perez to shoot him with a pistol as he held tome in front of his chest.

He presented her another with a bullet hole on one side and no exit hole as proof of his plan that it would work, police said.

''Me and Pedro are probably going shoot one of the most dangerous videos ever,'' Perez wrote on Twitter prior to performing the stunt.

''HIS IDEA not MINE.''

With video cameras recording, Perez pulled the trigger from about a foot away,  according to the authorities.

The bullet pierced the book and fatally wounded Ruiz. He died at the scene of a single gunshot would to his chest.

In a deal with prosecutors, Perez agreed to serve three months in jail in one-month increments over three years, and then serve the other three three months under house arrest.

She will also be subject to 10 years of  probation and lifetime ban from possessing firearms.

The couple's YouTube channel is still active and its 18 videos have generated 4.7 million views.
