Fans were disappointed earlier that 2AM weren't listed as the opening guests together with 2PM for the Wonder Girls' American tour this June. This was because 2AM had been announced to be going in the first announcement. But fans were surprised when Yenny of the Wonder Girls twitted on April 13th that 2AM will be opening for the Wonder Girls on their tour. The opening and not opening saga took another twist when Yenny twitted again on April 17th that 2AM won't be appearing afterall. So the final conclusion, 2AM will be in America but for JYP's concert only in May.
