Beyoncé is a lamb!

Queen Bey took to Mariah Carey‘s “All I Want For Christmas Is You” show at New York City’s Beacon Theater on Sunday — and snapped a selfie with the star backstage.

“I love you @Beyonce thank you sooooo much for coming out tonight,” Carey wrote alongside a photo of herself with the “Hold Up” singer, including a slew of emojis.

In the photo, Carey sported a shining, cleavage-baring top while Beyoncé opted for a black jacket with a matching hat and top.

The selfie is rare for lowkey Beyoncé. But with Carey’s stint at the famous theater lasting just a few more days, it seems the “Daddy Lessons” singer just had to catch the show before it ended.

Beyoncé wasn’t the only star to head to Carey’s holiday concert. On Saturday, Andy Cohen uploaded an Instagram video of the star singing her famous track, “All I Want For Christmas is You,” while wearing a sparkling, red leotard.

“Ok, Mariah!” Cohen captioned the photo, including Christmas tree and snowman emojis.

The show will head out of town on Dec. 17.

While many have showed up to the theater for a glimpse of the legendary singer, all eyes have been on Carey and her new beau Bryan Tanaka in recent weeks.

The pair’s chemistry has been visible as they’ve danced alongside each other, holding hands on stage at the show.

They’ve fueled romance rumors in recent weeks with a Thanksgiving weekend getaway and date nights in Los Angeles.

The new romance comes on the heels of Carey’s split from her Australian businessman James Packer. The pair broke off their engagement in October.
