The Yes Day star looked to be loving Carey's performance of her classic festive track "Christmas (Baby Please Come Home)."

Feeling the love, Carey — who is known as the "Queen of Christmas" — wrote back in response, “Thank you @jennifer.garner for being so festive!! ❤️🎄." She also reposted Garner’s video.

Carey performed the first of 16 shows of her Merry Christmas One and All! tour on Nov. 15 in Highland, California. The legendary singer will continue to perform across the United States and Canada until the final show of the tour in New York City on Dec. 17.

Other notable names who soaked up the holiday spirit at Carey's Hollywood Bowl show included sisters Kim and Khloé Kardashian and their mom Kris Jenner. Children Chicago and True, both 5, North, 10, and Dream, 7 also joined in the fun.

The famous family also got to take a photo with the "All I Want For Christmas Is You" star backstage, where they were joined by Carey’s 12-year-old daughter Monroe.

Garner’s festive outing comes as she gears up for the release of her new Christmas movie, Family Switch.
