Pictures from the Audio Technica Press Conference
She's back to her conservative look. It does nothing for her. Still wearing the headphones on her hair rather than on her ears, but I guess it looks more fashionable like that. In one of the pictures, doesn't she look like an elf? There are tons more pictures at BJJ. They all look the same though. She's either singing, sitting, or standing there for the pictures.
Here's a link for the commerical.
MF Provided by kyo_jieming2000. She's singing Meri Kuri ~New Best Album version~. You can't hear it though. The real CM will be out tommorrow.
edit. The new best Album has been confirmed. The album will contain new versions of songs. No confirmed date, but somewhere in the beginning of Spring.
