With all the success they have had being an international boy band it is easy to forget that One Direction are still young lads.
Yesterday, however, the X Factor stars reminded fans and photographers of their age as they goofed around in New York.
The boys had performed at Radio City Hall earlier in the day and were heading back to their hotel when Niall Horan and Liam Payne began to mess around in their van.

Fun times: The two boys kept themselves entertained and made each other laugh as they headed home
Niall, 18, started off proceedings by play fighting with Liam, also 18, as they were surrounded by screaming fans.
The blonde haired singer then jovially pushed and pulled Liam, before his band mate began to jokingly look alarmed while pulling funny faces and giving the thumbs up.
It's not clear exactly what Liam was saying but it had Niall cracking up and falling over with laughter.

Hello ladies: The cheeky boys were not overwhelmed by their screaming fans and took it in their stride
While those two were busy entertaining themselves, Harry Styles looked a little tired of the routine and barely cracked a smile as they arrived at the hotel.
The Brits award winners have proven to be quite a hit in the States and have been steadily busy for the past couple of weeks.
After missing several dates on tour in the USA with his band-mates, Zayn Malik got firmly back in the swing of things with the band.

The Bradford based singer had to rush home last week following the death of his aunt but was welcomed back to the fold and continued the promotional tour with the other four members.
One Direction have already appeared in a Nickelodeon TV show called iCarly and their stock is set to rise further as they have been confirmed to perform at Nickelodeon's Kids' Choice Awards.
The lads even feature heavily in an advert for the awards show alongside Hollywood heavyweight Will Smith, in which they kidnap him and take the actor to the main office where they show him what they have planned.

The boys may have girls clambering for them on a daily basis now, but, they are still getting used to all the fame.
Niall Horan tweeted: 'It was cool to just chill and walk around NYC, carefree, never really get t see much of cities we go to , but things have changed haha'. (sic)
He added: 'Who would have ever thought, that us 5 kids could ever get spotted in the streets of NY ! #dreamscometrue'.
