Да, Долорес отравилась в России.
Итальянские фэны поговорили со Стивом и он сказал, что Долорес стало очень-очень плохо после того, как она что-то съела в России.

Ее постоянно рвало.

При этом Долорес просила передать, что через пару дней она будет в порядке и продолжит тур в Швейцарии.
Вот, что пишет один итальянский крэнфэн:
hello everybody. just a post.
I just come back home from Florence. We met Steve and Marco at the hotel in Modena after the bad news came up. The manager and Steve told us that
Dolores was very very sick because of a bad bad meal he had in Russia. She kept vomiting (is it English? I don't know, I'm not here with my mind, sorry). We were very worried for Dolores health. But she told us that she will be ok in a few days and that Basel (and the rest of the tour) is still on.
I will leave home in a couple of hours to go to Germany. We had a great time anyway, Steve and Marco were so nice (as always) and I'm so relieved that Dolores is going to be ok.
So, goodbye, hope to be able to attend at my first concert, at the end.
Mannheim, I'm coming.
