Taylor Lautner has admitted that he struggled not to laugh while shooting the birth scene in The Twilight Saga: Breaking Dawn - Part 1.
The actor reprised the role of Jacob Black in the penultimate instalment of the hit franchise and he found himself having to perform CPR on Kristen Stewart.
And while the scene may come over a little gory in the movie the actor admits that it was fun to shoot.
Speaking in a behind the scenes video for the DVD the actor said: 'Sometimes it was hard to keep a straight face.
"There was one point where she stops breathing and she's out of it and I have to give her CPR.
'There was some moments during that where we just couldn't keep straight faces because she's just like dead.
'It ended up working but it was funny at moments.'
The final instalment of The Twilight Series will hit the big screen later this year.
Away from the series Lautner has also been linked to Incarceron.
