Harry Styles was left looking gob smacked as Louis and Zayn play a trick on the rest of the band.

One Direction's Harry Styles was left stunned and relieved after band mates Louis Tomlinson and Zayn Malik played a prank on the rest of the group with the help of Nickelodeon recently.

The 'What Makes You Beautiful' stars enlisted the help of a fake pregnant producer to fool the singers into thinking she was heading into labour.

Immediately as the woman showed signs of giving birth, Harry can be seen with a look of horror as he helps to console her whilst Niall runs for help and Liam attempts to call her husband.

Louis can be heard joking around as he makes a remark at the woman passing wind and Zayn keeps fairly quiet so as not to spoil the surprise.

After the reveal, Harry buries his head in his hands as the rest of the group tease him about his reaction during the prank.

At the end of the footage, Harry can be heard stating how he was thinking about what a fantastic press story it would have made.

Meanwhile, the band scooped three prizes at the Teen Choice Awards 2012 in Los Angeles last night (22nd July) and delivered a hilarious special acceptance video message as they were unable to attend the star-studded spectacular.
