Jennifer Aniston had trouble shooting 'Office Christmas Party'

Actress Jennifer Aniston says filming Office Christmas Party was very hard as the cast and crew of the movie couldn't stop laughing during funny scenes.

The 47-year-old actress, who plays a grumpy CEO in the new festive movie, has revealed T J Miller and Kate McKinnon were responsible for her distraction, reported Femalefirst.

Adorably, Kate had a really hard time keeping a straight face, so that would send all of us laughing and there were a lot of people in that room. "They're all so funny, Kate obviously, TJ (Miller), they're all funny, it was just wonderful, everybody's cheeks hurt that day."
