Robyn has already "made it" and toured America several times. Katy shouldn't have taken that tone with anyone, much less somebody who's been in the business much longer than her and who is much more respected.
Sorry, but I'm tired reading stuff like "Who's Robyn?" or "I'm only here for Robyn Fenty" and stuff...What do people on a music board when they never heard of Robyn. I mean, she's not THAT "Indie" anymore...
