Helene Fischer has been advertising for Lidl for a few days now. But for that, the pop queen has to listen to scorn and ridicule from many fans.

"I think I've discovered a whole new form of foreign shame," complains one user, "I'd rather go to Aldi." According to a new ranking, however, Helene Fischer is no longer the most successful German singer of all time. The campaign with a star cast has already achieved its goal: Everyone is talking about LidL.
