Good looks, adoring fans, global hits and a sold-out world tour.
And now they appear to have the capability to be in two places at once...
The band today found themselves in the middle of another X Factor controversy thanks to their Saturday night performance -- while they were tens of thousands of miles away in Los Angeles.
Although host Dermot O'Leary never actually said the band were singing live from the studio, he did give them a thumbs-up.
It turns out that the band did a pre-record on October 30 -- and the judges are seen giving them a standing ovation wearing the same outfits then as they did on Saturday night.
It's no secret that Irish teen Niall Horan and his band are stateside and they have made no attempt to hide where they are.
Indeed, just a few hours after the UK broadcast, bandmate Liam Payne was pictured on the balcony of the London Hotel in the City of Angels, putting paid to any suggestion that they were back in the UK.
And as the band's new single Little Things was aired on the show, Niall, Zayn and Louis were spotted across the Atlantic, prompting the revelation that the performance was recorded on October 30.
Saturday's show was described as "live from London" and the judges wore the same clothes as they did for the recording, leading criticism that show bosses intended to deceive viewers.
Fans have criticised the show for giving the impression that the five lads were live in the studio during Saturday's show.
Host Dermot told viewers: "We have been celebrating the best of British tonight and they don't come any bigger or any more British than our next special guest."
An X Factor spokesman has defended fakery allegations, stating that they added to work around the schedules of the superstar band, who are currently taking the US by storm.
"One Direction were pre-recorded as they are out of the country this weekend. The X Factor played it out as live but we have never tried to hid the fact it was a pre-record."
While the flagging show was dealing with the latest fakery row to mar the series, One Direction were riding high as they collected two awards at the MTV Europe Music Awards on Sunday night.
The band, which also includes Harry Styles (18) and Liam Payne (19), won Best New Act and Biggest Fans in Frankfurt.
As their star continues to rise, so does their earning power and the band have an estimated fortune of more than €30m.
