One Direction's On The Road Again Tour is still underway in North America and the band just played to a stadium crowd in Buffalo, N.Y. Thursday night.

One Direction Launches 'Dear World Leaders' Video, Using Fans' Contributions From Action/1D

There was a girl group member in attendance at this show. It was Fifth Harmony's Camila Cabello!

Cabello is the envy of many girls around the world right now since she not only got to watch Harry Styles, Niall Horan, Liam Payne and Louis Tomlinson put on a great show, but she got to hang out with them backstage too.

One Direction's Liam Payne Is Officially 22 & He Had A Pretty Sweet Birthday!

It seemed like she mainly hung out with the Irish member backstage, but still, it's pretty epic!

At the end of the night, Cabello tweeted the lads, "AH didn't get to say bye but the show sounded amazing tonight!!!!"

"SMASHED IT," she concluded.

Horan instantly tweeted her in return and there is even more envy there since he called her "darling" and admitted it was "fun" that she was there.

Cabello beamed over that with a "yay" followed by a lot of exclamation points.

Horan even took to Instagram to show what they were up to backstage. Cabello rode around on his Segway and it looked like a total blast! The two shared a bunch of laughs as seen in the Instagram video Horan posted below.

The 5H member also shared the video Horan posted, but in the caption joked, "I just might get my Segway license faster than my real license."

Camila, next time you go to a 1D show, please invite us!
