The First Lady is officially on Twitter.

@MichelleObama wrote her first tweet on Thursday morning at 8 a.m. ET. In a second tweet, she announced that the social media account will be managed by campaign staff, with any tweets from the First Lady herself signed '-mo.'

We're excited today to launch @michelleobama as a new way for you to connect with First Lady Michelle Obama and the President's campaign, the tweet read.

The president was among the first to welcome Michelle to the social networking site. It's not every day we get to welcome the First Lady of the United States to Twitter-happy to have you, @MichelleObama! tweeted @BarackObama, an account run by his 2012 campaign staff.

President Obama already has a strong social media presence. When he ran for the White House in 2008, he was the first presidential candidate to embrace Twitter, Facebook and other forms of social media to connect with constituents. In November, the Obama 2012 campaign started a Tumblr account, where they regularly posts videos and rebuttals to GOP rivals.

In her profile picture, Michelle has an Obama Biden banner, signaling the account will be used for re-election effforts.

Within two hours of creating the handle, Michelle already had 15,000 followers -- and that number is sure to climb tremendously. Many Twitterers had already welcomed her to the platform.

@michelleobama loved your dancing with the kids the other day. Welcome to Twitter, First Lady wrote  @stu_McAllister.

And of course, there were a few jokes.

This isn't Michelle's very first time on the platform. According to the White House blog, she sent out her very first tweet from the @JoiningForces account on October 20.
