And like a true friend, Camila has been there for Ariana in the wake of the horrific attack at her Manchester show last week.
Speaking to Britain's This Morning, the "Crying In The Club" singer spoke out about her friend.
"Yeah, I spoke to her after that happened," Cabello said.
"I'm so sorry, I can't even imagine."
The hosts then asked the singer how Ari sounded when she spoke to her.
"[She was] so shaken up. I mean, what can you say?" She responded.
It's good that Ariana has such an ~amazing~ friend to lean on in this tragic time!
