When you have 5.5 million followers on Twitter, you have to be mindful of your words.

When you're Charlie Sheen, mindful and words don't belong in the same sentence.

Charlie Sheen had a big Oops moment last Thursday when he accidently gave his private phone number publicly on Twitter intended for Justin Bieber.

(Still not sure what's worse: Tweeting your phone number on accident for all to see or giving your number to none other than the Biebs).

310-954-7277 Call me, bro. C, Sheen tweeted in what could be determined as his best #winning-worthy moment yet to date.

The tweet was also immediately deleted and Sheen's personal number was changed. However, according to a report from the New York Post, Sheen received 1,800 text messages and a flood of phone calls after the incident on Thursday.

Witnesses said Sheen answered the phone calls with Ray's Pizza or Winning.

The latest Sheen flub happened on Thursday while he was eating dinner at a Guy Savoy restaurant in Las Vegas, according to a witness.

But his phone just continued ringing and buzzing and eventually just completely melted down, an anonymous source told The Post. Charlie was, like, 'I guess I need a new phone.'

Sheen got himself new digits and continued to party in Vegas with friends, where he reportedly dined on caviar and black-truffle soup.

Charlie Sheen's publicist confirmed the Tiger Blood changed his number.

I haven't been able to get through to him on the phone since Wednesday, his rep told The Post. He just got a new number.

Better luck next time, pranksters.
