Charlie Sheen accidentally tweeted his phone number to his more than 5 million Twitter followers while attempting to send a direct message to Justin Bieber.

Sheen — who first joined Twitter earlier this year — was eating dinner at elite French restaurant Guy Savoy in Las Vegas last week when he sent the pop star a message to give him a call.

"310-954-7277 Call me bro. C," Sheen tweeted.

Although the message was intended to be privately sent to Bieber, Sheen actually sent his digits for all to see. It was promptly retweeted by Sheen’s followers. The number has since been disconnected, and the tweet has been deleted.

According to the Daily Telegraph, a source at the restaurant noted that Sheen’s phone received a flurry of calls and text messages. “Charlie saw the funny side and answered the phone a few times, saying things like 'Ray's Pizza' and 'Winning,’” the report said.

It isn't the first tweet accidentally sent by a celebrity who thought he was sending a direct message. The infamous Twitter-based photo that led to Congressman Anthony Weiner's resignation was also intended to be a DM.

This incident also begs a very important question: Charlie Sheen and Justin Bieber are friends?
