Rebecca Black 'doesn't understand' death threats

Rebecca Black has said she doesn't understand why her song 'Friday' has provoked several death threats.

Earlier this week, it was reported that police in Anaheim are investigating threatening phone and e-mail messages levied against the 13-year-old singer.

In an interview with Extra, Black told host Mario Lopez that she can't comprehend what she has done to elicit violent reactions from the public.

"I think that's kind of weird," the singer commented. "It's a song. It's not like I ran for president and then I said something really bad... What did I do? I sang a song about a day."

While the musician has received some harsh criticism since releasing the song last month, she has also garnered support from the likes of Simon Cowell, Miley Cyrus and Nick Jonas.

Black also expressed enthusiasm over reports that that the cast of the hit Fox sitcom Glee plan to cover 'Friday' on an upcoming episode, adding that she hopes Chris Colfer's character Kurt takes on lead vocals.

"I really like Kurt," she beamed. "I'm a Kurt person, so that would be really cool!"
