One Direction member Harry Styles and 'Harry Potter' alum Emma Watson. It's match made in PR heaven -- or a match made in Taylor Swift hell, depending on who you're talking to.

Justin Bieber's social media efforts have paid off. The 18-year-old singer is officially the most-followed person on Twitter, dethroning fellow pop star Lady Gaga.

It didn't take long after Lance Armstrong told Oprah those words everyone had been waiting years to hear -- yes, he doped during his illustrious cycling career -- before Twitter lit up with reactions. When we weren't taking shots or playing bingo, we complied some of the better tweets we saw.

One Direction meant well when they tweeted about their visit to Ghana as part of their involvement with Comic Relief, a U.K. charity that sponsors Red Nose Day, a telethon that helps provide support for impoverished regions of the world through comedy. When Niall Horan tweeted about the poverty and the slums he saw, it ignited a backlash from Ghanaians who felt that his perspective was skewed and

Have you been on Twitter lately? It's really just a repository for Manti Te'o jokes. Ever since it was revealed yesterday that Te'o's story about his perfect girlfriend dying of cancer was a big fat sham (for the full story, this is a good source), the only purpose anybody has to go on Twitter right now is to make jokes about it. Here are some of our favorites, although there are so many it's real

Thanks to the rise of the social media site Twitter, celebrity users and your every day folk like you and me are closer than ever.

Universal Pictures Hey, did you hear about the Oscar nominations? We're guessing Ben Affleck isn't the only one crying -- hordes of musical theater fans are losing it too.

Since Twitter is the No. 1 way to insult celebrities directly, late night talk show host Jimmy Kimmel once again asked celebs to read mean tweets about themselves.

Azealia Banks is Twitter beefing again -- this time against up-and-coming rapper Angel Haze. According to The Drop.fm, the bickering is over a tweet the '212' rapper made about Haze not being a native New Yorker.

Twitter has been giving celebrities a platform to air their opinions and what they ate for breakfast since 2006, and boy have they. It's also given them a place to interact with other celebs and share their grievances with one another. This of course has inevitably led to a new form of communication: The Twitter slapfight, in which stars duel over the internet in 140 characters or less (often to t

He may not have been nominated for any Grammys or topped this year's Google searches, but at least tween sensation Justin Bieber won where it really counts: on Twitter.
