It also isn't doubtable since she has had them open for her. It could be old news/she wanted to; either way it was just released today that she wanted to.
As Us Magazine reports, J-Splif of Far East Movement said of working with GaGa: "Being able to tour with Lady Gaga was a crazy experience. It was actually our first time out in Japan, and to just to see her get down as Lady Gaga -- from her sets, to her costumes, to her songs, everything is put together so well. It is almost like you are watching a circus slash theater type of show. You are sitting there for 2 hours and you get worn out from the whole artistry of it. It's just her working so hard and being such a humble sweet person."
When asked if they obtained any great advice from Lady GaGa, Kev Nish revealed it to be: "For instance, we were backstage with Lady Gaga and in her recording studio she has built in these arenas. She just said 'keep your ears to the streets and to the clubs and to the people that have supported you from the beginning.' We practically live in the club, as much as our record is not 100% a dance record, it is heavily inspired by dance. Always keeping in tune with what's hot and what's new is very important."
