Mariah needs to stick to what she knows best in the states and that is much smaller venues.
Looking at her recent concert stats (supported by huge hits), she mostly did theaters with mediocre tour grosses and arenas might be a little over her head in terms of fully selling out shows this time around.
That's a funny thing to say from someone who literally has NO power whatsoever.
I'm not even a Mariah fan, like at ALL, but you have to give her props for keeping her new single in the top 20 after the number of years she's been in the music business.
And Perez, you don't need to be giving anyone advice until you fix that retched dirty mop on your head that you call your hair.
