Nice if it happens, though I don't like how things are being done. All this rallying on Twitter when Gaga's staff already seems reluctant to reply just seems really unprofessional to me. Like trying to push things by bringing it into the public eye. I mean, yeah, things get done sometimes through Twitter (eg ayumix7) but it's not the solution to every problem...
Besides, where and when did ayu say yes??? I've looked through the official website, TA, her Twitter, and I've seen nothing about it. She hasn't even tweeted a single thing about it, which is strange if she's already said yes personally to Leslie. Normally she'd be really supportive and tweet herself about these things...
