Band fool around at Heathrow

One Direction touch down at Heathrow in London on 16 May 2012.

After a trip to Sweden where the boys were busy working on new music, One Direction appear to be in high spirits.

Handsome Harry Styles flashes a sweet smile as he strolls through the airport flanked by female fans.

Favouring a dressed-down look, Harry teams a baggy black knitted sweater with loose-fitting dark trousers.

The sexy star keeps his trademark curly locks hidden beneath a cool khaki beanie.

Liam Payne looks just as excited to be back in the UK.

The cheeky One Direction star – who sports a grey hooded zip-up sweater and plain tee – hitches a ride on band mate Louis Tomlinson’s trolley.

Louis doesn’t seem to mind the extra weight though as he allows Liam to make himself comfy alongside his holdalls.

Disaster almost strikes when a fan thrusts her phone and Louis, causing Liam to wobble. Luckily the singer manages to find his balance.

Niall Horan is the next member of the group to be spotted by admirers.

Judging by the wide grin on his face, it’s clear the Irish blond has had a great time laying down One Direction music with his pals.

Zayn Malik seems keen to prove that he hasn’t been changed by fame when he emerges in the capital.

The heartthrob is more than happy to push his own luggage towards the lads’ car.

Just like Louis, Niall, Harry and Liam, Zayn goes for a low-key vibe in a grey hat, two-tone varsity jacket and bright top.

The group kick of the North American leg of their Up All Night tour later this month.

It’s likely admirers will be wondering if they’ll be treated to any new One Direction music when the lads hit the stage.
