Police are investigating two death threats against Rebecca Black, the California teen whose annoying YouTube music video “Friday” went viral in March.

Reuters reports that the Anaheim Police Department is investigating two threats against the 13-year-old, which were made in March after “Friday” became an internet sensation.

“In essence the threats were related to getting the music off the Internet or they were going to kill her,” said Anaheim Police spokesman Rick Martinez said.

“We can’t validate how serious they are, but we do take it seriously.”

According to Martinez, one of the threats was made by phone, the other by email. Both were made through Black’s production and management companies.

“We’re going to investigate and determine, number one, the source of the comments and then based on the investigation determine what intent was and where we go from here,” he said. “If we believe they were actually intended as threats we will work toward prosecution”

While the investigation takes place, he promised officers would be “keeping an extra eye out” for the middle schooler. Once the perpetrators are identified, they could face criminal charges, he added.

Now, I know “Friday” grates on the nerves, but death threats? Come on, people. She’s 13 for cripes sake!

And you have to give her credit – that insidious video has generated more than 200 million views, according to Visible Measures.

Incidentally, that’s more than her idol Justin Bieber’s “Pray” video AND Lady Gaga’s “Born This Way.”

Which you have to admit is impressive. Deeply, deeply disturbing…but impressive.
