selena-gomezLOS ANGELES — Three celebrity swatting incidents in 2 days have police on edge.

The latest case involves actress Selena Gomez.

According to TMZ, a swatter called 911 and told the dispatcher… her dad killed her mom with a gun that was among a cache of 20 weapons located inside the Tarzana home.

The swatter then said the dad was going to burn the house down.

That incident came less than 2 hours after a similar report at the home of Justin Timberlake in the Hollywood Hills.

TMZ reports that in this case, the 911 caller claimed 4 black males entered the house and 2 shots were fired and they left a box with red blinking lights.

On Thursday, a 911 caller reported that someone had been shot inside the Pacific Palisades home of singer Rihanna.

In the Rihanna case, emergency dispatchers received the call shortly after 3 p.m. Thursday reporting that someone had been shot and wounded inside the singer’s home in the 900 block of Rivas Canyon Road, said LAPD officer Bruce Borihahn.

Officers secured the location and quickly determined the call was a hoax.

Rihanna, whose real name is Robyn Fenty, was not home when police responded to her home.

The incident comes a day after someone contacted police saying there was an assault at Sean Combs’ Toluca Lake home. Combs also was not home at the time and police found no evidence of a crime.

No one was hurt in either case, but police said those who engage in swatting — which gets its name from the large tactical response that can occur in such cases — should be prosecuted to the fullest extent of the law.

The increasing number of such incidents targeting celebrities has California lawmakers considering implementing harsher penalties for such crimes.

Rihanna’s boyfriend Chris Brown was also a recent victim of swatting, when someone contacted police and reported domestic violence and a possible shooting at the singer’s Hollywood Hills home.

Before that incident, a caller falsely reported shots fired at actor Tom Cruise’s Beverly Hills home.
