Justin Bieber Prank Ticks Off Grandma

It may have been a harmless prank when Justin Bieber tweeted an almost comlete phone number to his fans to call him, but an 81-year-old woman isn't laughing. INSIDE EDITION has the scoop.

Attention Justin Bieber—there's at least one red blooded American woman who hasn't been struck with Bieber fever.

A tough-talking Texas granny has plenty of reason to be ticked off. Her phone has been ringing off the hook because of Bieber's prank-gone-wrong.

Earlier this month, the Biebs tweeted: "Call me right now..." Then gave the area code for Dallas, 214, along with six digits and a question mark. Not a complete phone number, but that didn't deter devoted "Bielebers." They dialed all 10 possibilities for that last digit. And one of those phone numbers belongs to 81-year-old Dilcie Fleming.

"I think he's just a fly-by-night kid making oodles of money," said Flemming.

One caller left a message saying, "I love you so much, and I want to have your babies!"

Another caller said, "I love you, I love you, I love you! Justin, I love you so much!"

"Just one after the other," said Flemming. "I'd hang up and it would ring again."

Another caller said, "Justin, oh my god, call me back! I love you!"

Flemming said, "I did tell one young lady, 'You just don't realize he has no interest in you whatsoever.' "

Flemming also changed the outgoing message on her answering machine to say, "This is not Justin Bieber's phone number."

Now she's hired an attorney and is considering a lawsuit against Bieber for disrupting her retirement. But, she says, she'd settle for an apology.

Oh, and there's one more thing—concert tickets for her great-granddaughter.
