meisa will be a guest on this sunday's MUSIC LOVERS with arashi! i dunno if she'll be appearing as a guest or she'll just be a guest shown by a VTR or something, but the translation told me it's not a song appearance, though, so...can't wait to see meisa!
and meisa was a guest on himitsu no arashi-chan yesterday!
