SelenaDreams really do come true. Backstage at the iHeartRadio Jingle Ball hosted by Z100, Selena Gomez bumped into Fifth Harmony. While the mere presence of these superstars is amazing in itself, what happened next is the stuff of fandom dreams.

While photographers called for a few quick snaps, Selena hugged Camila Cabello, saying, “I’m Sixth Harmony.” Um, yes. That happened and we have the video to prove it. You can check out the magic below.

We’re already picturing a collaboration of epic proportions (“Good for You” meets “Worth It”? Yes, just … yes). However, that’s not the only amazing Fifth Harmony-related moment captured backstage. The quintet also casually slayed a cover of Mariah Carey’s “All I Want for Christmas Is You.” It was epic. It was a capella. And it was everything. Spoiler: They hit that high note at the end of the song. You can check out that clip in the video below.

Now picture that performance with Selena as the sixth member of the band. Can you handle it? Because we sure can’t.

If you missed out on all the action, consider this your holiday gift. You'll be able to relive the night on The CW during a special 90-minute broadcast on December 25th and 30th at 8 p.m. ET/PT -- so put on your Santa hats, grab some gingerbread cookies, and tune in!
