Nickelodeon played a prank on One Direction during a TV appearance last night, and poor Harry Styles had a little bit of a freak out!
The channel got fellow Directioners Zayn Malik and Louis Tomlinson in on the prank - convincing the other boys that a woman was about to give birth right in front of them.
Before the show, Zayn said "We're going to have a bit of fun with it and see what their natural reaction is."
An actress was hired to impersonate a producer with a huge prosthetic bump - and then pretend to go into labour while the boys waited on set.
Almost immediately she claimed to be feeling uncomfortable. The boys tried to seek advice before realising that they were alone in the building with her.
As her act got more intense, adding some screaming and crying to the mix to convince them that she was experiencing labour pains. Harry began shouting "Why is no-one here? Can somebody help us?"
Liam Payne tried to make her comfortable, before being given the task of calling her husband, who we assume must have been in on the act - bit cruel otherwise!
He said "We're with your wife and she's in a lot of pain. We know she's pregnant and she might be giving birth."
Eventually the actress revealed that the boys had been tracked, as Louis and Zayn emerged laughing, high-fiving and hugging. Honestly boys, you really can't stop hugging each other, can you?
Harry was a bit overwhelmed, collapsing to the floor as Louis said "Harry was the worst! You were so embarassing!"
But it turns out Harry wasn't really thinking about the poor producer - "I was actually thinking, 'This is going to be a great press story; One Direction deliver a child.'"
Happy Two Year Anniversary Boys!
