Katy Perry and Orlando Bloom have the CUTEST Christmas tradition — and it involves Prince Harry and Meghan Markle!

The Teenage Dream songstress performed onstage Wednesday night while recording her ITV Christmas Special in London, and she revealed some fun plans she has for the upcoming holidays.

She told the crowd she wants to dress up as The Grinch and go caroling in her neighborhood:

“We are going to be home in America and actually we are going to do something we do every year. We rent a trolley and we dress up, and there’s lights on the trolley, and we go to all of the neighbors in my home town and we see all of their lights. Sometimes there is hot cocoa and I’m dressed like The Grinch and it’s going to be super fun. We go caroling. We are going to go and knock on people’s doors and do some carols.”

How do the Duke and Duchess of Sussex come into play, though? Well, they’re not only good friends of Katy and Orlando — they’re also neighbors! So they’ll be hearing some of that sweet caroling and seeing the trolley pass by! How cute.
