Okay, so firstly, we're a little bit jelly that Sofia has met Taylor Swift (and let's face it, probably Shawn Mendes) — and actually managed to keep her cool.
But also, we can't blame her for losing her composure when meeting Billie — the girl's an icon!
Of course, Billie reacted to the meeting in her usual humble style.
“We were doing the [Elle] cover and she was performing and I was gonna be after her and she was super cute,” she told Entertainment Tonight.
“She was with her little sister and her sister started sobbing cause of me and it was like insane. I was like, ‘Your sister’s Camila Cabello though, why are you crying for me? What?
TBH, we'd probably be besides ourselves if we met Camila, Taylor OR Billie. We're not picky.
It comes amidst whispers that Billie and Camila are working a collab RN.
After Camilla met Billie herself, she posted a pic of the two together, sparking rumours the pair have something up their sleeves.
While Camilla confirmed at the time that they didn't have anything in the works, you never know who will pop up on her second studio album.
And if that happens? Safe to say we'll be crying happy tears, too.
