What iPhone Does Ariana Grande Have?

I think she has a iPhone 6 but I'm not too sure. If she does, do you know what colour? And can you tell me what case she has?

Google

She has the 8. But you can't have one.

She's got a flip phone. Charcoal grey. Standard. Cheap. The color of her case is transparent.

In fact, i think its a trac phone. Could be boost mobile? Or maybe metro pcs.
