Katy Perry celebrated the holidays early last weekend (12-13Dec15) by inviting more than 100 loved ones to attend a private screening of festive classic Home Alone.

The pop star rented out Los Angeles' Vista Theater on Sunday (13Dec15) to host a pyjama part of sorts after handing out onesies as gifts for her family and friends to change into.

They were also treated to warm winter beverages, including hot chocolate for children and hot toddy cocktails for adults, and snacks including pizza, popcorn and candy as they settled in to watch the 1990 movie, which features Macaulay Culkin as a young boy who gets left behind by his family over Christmas.

"It's one of Katy's favorite holiday movies," an attendee tells Us Weekly. "So she decided to screen it as her holiday party this year...

"Katy was milling about in the lobby. At the beginning of the screening, she said, 'Thanks for coming. I'm bad at public speaking. Enjoy the movie!'"
