Miley Cyrus, Cody Simpson and Billy Ray Cyrus had an all-out jam session during a charity benefit.

Miley's nonprofit, The Happy Hippy Foundation, held its annual holiday party on Friday (December 13) at  My Friend's Place, which is a shelter that combats homelessness. The "Slide Away" singer along with her father and boyfriend performed an acoustic set for attendees. The trio was also joined by Miley's sister, Noah Cyrus, and mother, Tish.

Even attendees from Miley's foundation joined in for a rendition of "Silent Night." The family then gave a rousing performance of "Old Town Road" featuring a clarinet solo. Lil Nas X, the original artist, even left a comment of heart-eye emojis on the post.

"Holiday party was a success once again," Miley wrote in an Instagram post. "🎄 always blown away by the young people I meet at MFP [My Friend's Place]! There is always so much love and talent! Thank you to everyone who joined us in celebrating this special time of year with HH! 💛 #happyhippieholidays."
