The raven-haired beauty and her Hollywood actor boyfriend attended her actress pal Shannon Woodward's bash, and the 'Lord of the Rings' star got fully involved with the singing, belting out a version of Avril Lavigne's 2002 hit 'Complicated'.
Katy, 32, shared a Snapchat image of Orlando, 39, bellowing out the big pop tune complete with the caption: "This is what the holidays looks like (sic)"
Other stars at the event included Shannon's 'Raising Hope' co-star Kate Micucci and TV personality Ronan Farrow, who shared an Instagram video of Katy leading the group in a version of Alanis Morissette's 'You Outta Know'.
He wrote: "@agreenersean and @katyperry killing it on the Alanis. (sic)"
Ronan - the son of Woody Allen and Mia Farrow - also posted pictures of the event.
He captioned two photos of the group: "When your friends commit to the Karaoke (sic)"
Katy recently praised Orlando for being so "kind" and admitted he has taught her a lot about being a UNICEF ambassador.
She said: "He's been a UNICEF ambassador for over 10 years and I've only been a few years so he's kind of shown me some of the ropes.
"Everyone is a teacher in a relationship, that's how I see it now. We've taught each other a lot."
Last month, the couple sparked speculation they had got engaged when Katy was seen sporting a jewel on her wedding finger in New York City.
A source said: "She [Katy] walked with her left hand leading her, and bent her hand to show off the large sparkler to the cameras. They seemed proud to show off their happiness ... Katy's mood was better than [I] had seen before. Katy was happy and laughing, joking with Orlando and pals as they got into the car. They seemed proud to show off their happiness."
