One Direction

If rumors are to be believed, not only would Taylor Swift not put out enough for One Direction's Harry Styles, but she also just didn't want to go out enough, either.

And so it begins! Taylor Swift revealed that she's back in the studio, fresh off her split with One Direction heartthrob Harry Styles.

Let the songwriting commence. It looks like she really did know he was trouble when he walked in…

One Direction were saving the best for last! The band released yet another 'Kiss You' video teaser, and this time there's a lot of shirtless action. Glory!

Haylor ended 2012 and entered 2013 with a romantic kiss. Taylor Swift, who performed on 'Dick Clark's New Year's Rockin' Eve' before the stroke of midnight, and boyfriend Harry Styles of One Direction shared a romantic kiss at midnight on New Year's Eve in New York City. These two kids – so in love!

Congrats to Adele, Taylor Swift and One Direction! The trifecta of pop perfection were the highest selling artists worldwide of 2012. Is anyone surprised?

One Direction came together to raise $2,000 for an Alzheimer's Disease charity. The cause hits close to home for the 1D boys, as Eleanor Calder, the girlfriend of member Louis Tomlinson, has an Alzheimer's-stricken grandfather.

The once-friendly rivalry between the Wanted and One Direction has gotten heated in recent weeks, with personal insults on Twitter and threats of violence. The groups will be in the same building on Friday, performing as part of the Z100 Jingle Ball concert in New York City, but the Wanted's Max George says the dueling boy bands won't go near each other.

Say it ain't so! One Direction heartthrob Harry Styles was spotted at 'X Factor' rehearsals ... with Taylor Swift.

We know you all love One Direction, but Directioners and paparazzi -- please give the boys a break! Zayn Malik and Liam Payne in particular could use a little more consideration.

In the biggest shocker since Tom Cruise and Katie Holmes announced they were divorcing, we kid, Adele, Nicki Minaj and One Direction have some of the biggest-selling albums of 2012 according to the Neilsen SoundScan. So far. But don’t be surprised if these two stay on top for the long haul, because the youngins and not so youngins seem to love One Direction, Minaj, and Adele.
