yeah now she is.

In the US - yes

Yes

NOT WORLDWIDE!

Yes, Ariana is bigger than both of them, musically.
Although, Selena is a bigger celebrity than both Ariana and Demi.

Yes bigger than both combined

Right now yes for obvious reasons

overall no.

As of right now she is but, Demi and Selena have been around for quite a while unlike her.

Yeah obviously.

Waiting on that one Demi stan to spam those certifications in blue/red/purple font.

Right now, she is. Demi and Selena have been out for years yet none of them have been able to pull off Problem's first week sales, airplay or longevity. If her album follows in the same foot steps, she'll soon be up there with Miley.

Duh.

in the US, hell yes.
Selena is outside the US.

Ready for the stale Demi shade.

And for now, yes. I hope they can both coexist equally!

duh

This

This same thread is made every week and we'll see how her second album performs and also her tour. If she goes on one.
