Justin Bieber has found himself in hot water with a GRANNY from Texas!

Dilcie Fleming from Dallas has been inundated with phone calls from girls with Bieber-fever after the star Tweeted a Dallas telephone number with one digit missing and asking his legions of fans to call him (er, prob not your best-move ever, Jus...).

His 19 million Twitter followers immediately began hitting the phones and trying different number combinations hoping to reach their idol.

Instead, many of them called up OAP Dilcie.

"I had no idea what was going on," the elderly lady told ABC News. "I was told that this young man put a number of the tweeter, or whatever it's called, but left off the last digit. People were punching in until they got an answer."

Dilcie says she has been giving some of the callers a bit of advice - telling one young lady "you just don't realize that he has no interest in you whatsoever!"

Dilcie says the call are now slowing down, and whilst she is not planning to sue the young star, she would like an apology and some concert tickets for her granddaughter...

Priceless!
