They've only been famous for a year, but One Direction were welcomed with an A-list reception last night as they touched down on US soil.

The British boyband have flown across the Atlantic in a bid to crack the American market, including asupport slot on the Big Time Rush tour and a cameo stint on Nickelodeon sitcom iCandy.

An army of fans waited with placards at LAX airport - largely dominated by girls, but with a handful of boys too - hinting this year's X Factor winners Little Mix could be in for a successful future too.

Fleeing the UK couldn't come at a more opportune time for 17-year-old Harry Styles, as he attempts to mend his broken heart following his split with Caroline Flack.

Yesterday, Harry confirmed the pair had called time on their three month fling.

The singer, who will turn 18 on Wednesday, told fans on his Twitter page that reports of the break-up from 32-year-old Xtra Factor presenter Caroline were true.

However, Harry said he had not 'dumped' Flack, insisting the decision was mutual.

He tweeted: 'Please know I didn't "dump" Caroline. This was a mutual decision. She is one of the kindest, sweetest people I know.'

Harry and Caroline caused controversy when they started dating back in October due to the 15-year age gap.

But the pair ignored the criticism and have enjoyed a fun-filled fling over the past few months.

They consistently avoided being photographed together during their romance, with one of the only shots of the pair being a Twitter picture from the beginning of their relationship.

The pair were spotted leaving each other's houses in the early hours of the morning on various occasions, but they were said to have split over the new year.

However, Caroline didn't let her newly-single status affect her as she co-presented the ITV2's coverage of the National Television Awards on Wednesday night.

Stepping onto the red carpet, she wore a colourful dress with a pink shirt, and tanned pins on show.

She spent five hours in the hairdressers' chair, appearing with shorter, darker locks a few days ago.

And she'd clearly had a good time as she let herself loose following her presenting stint.

She tweeted the following morning: 'My.head.hurts.'

oh dont make a big deal out of it, its clear he wants to get on with the group and concentrate on the music. Just leave it now.

If they were that good, they'd have made it without a manufactured talent show. Just like REAL superstars have in the past (and will continue to do).

I feel sorry for Harry

Im a big 1D fan and actually they are really nice lada and they are talented. Yes they have good looks but thats not the only thing they have, they love ALL of there fans and they ALWAYS tell us how much they love us. They are always nice to their fans because they know that we have feelings, and they are especially nice to little kids. And Harry was upset that night because he has literally just broken up with Caroline Flack who i know he liked ALOT. One Direction gave me hope, they showed me that life was worth living and because of that i was able to stop self harming. So if you see them as a stuck up talentless boyband then fine, thats your opinion. But i know for a fact that they are nothing like that.

This story is identical to the one yesterday about them breaking up, just with a tiny bit added first. Can't the writers come up with something original.

It is almost exactly a year to the day since DM ran a similar story when 1D came back from LA to Heathrow, and hundreds of girls were there to greet them. Back then, they needed a police escort. This time around, almost no fan got to meet them due to security issues. I am happy One Direction are very successful but very sad for the American Directioners who waited for hours and hours only for the boys to slip out through a private airport exit. If that is progress, I am sad.

that's funny because as A big fan of One Direction, I know for a fact that they have never even done a book signing at bluewater! - Sarah, London - - - - - - 15th September 2011, so if your presuming i'm lying, dont.

Whats the thing with these nappy like trousers they wear and why are Harrys jeans so low? They look stupid and Harry could do with looking less miserable unless he thinks that looks cool aswell. - Susie, Oxford, 28/1/2012 14:34 -- He just got off a long flight. I'm pretty sure you wouldn't be a bundle of smile if you had just got of a long flight and were faced by a bunch of blinding camera flashes. Give him a break he's only human.
