Yes.

EDIT: I thought Kiss & Tell was Selena's best selling album

Yes

It is in the US but Selena was even more local back then so it didn't really sell much outside of the US compared to WTSGD.

I believe so

Yep. The only person who can outsell her at this point in album/single sales is Miley.

How much did Kiss & Tell and WTSGD sell outside the US?

she will but it will still be considered a flop

Yes

She will outsell Demi but not Selena.

Guess that's one of the downsides of being a main pop girl, the standards are higher for Ariana.

Nope, even with 4 hits on itunes top 10. Her album can't even reach top 10 with per-order.

Why would it be considered a flop?

It's so far reached #2 just based off of pre-orders...

Are you trying to tell me that DEMI sold more outside the US than in the US?
