Our take: As politicians and celebrities alike have shown — be careful what you tweet

For 81-year-old Dilcie Fleming of Dallas, a tweet from Justin Bieber caused her phone to begin ringing off the hook, and may in turn lead to legal action.

Beiber's tweet, sent out earlier in March, included a number with a Texas area code and said, "Call me right now." It gave a 214 number with a question mark in place of the last digit. Fleming and another man, who told ABC News his name was Kent, have received thousands of phone calls from Bieber's followers since then.

Fleming said she has no intention of having her number changed, and she has changed her outgoing message to say, "This is not Justin Bieber's phone number. Please do not call again."
