In every radio interview she made (and she made a lot already), people ask her about a tour and tell her she should definitely do one and they would support her. She answers "I guess I ought to do it one day" all the time, tho, which is not very convincing.
She's going to those 3 Sephora stores: New York, LA and Miami. Sephora is such a huge international chain, I don't know how can it not be good to do events there. Unless Sephora isn't as popular in the States as it is in Europe.
Besides that, in most radio interviews throughout the country people/fans have been able to go there and meet her or phone the show and talk with her. The next radio stations she's going to are Portland, Reno, Sacramento, San Francisco and Los Angeles. And probably more afterwards, I guess.
