Rip Slyme
In February 2010, it was reported by "Josei Seven" magazine that Otsuka was dating rapper Kazuto Otsuki (publicly known as Su, member of hip hop group Rip Slyme), with whom she collaborated in October 2009 for her song "Aisu x Time". Neither of the artists' agencies would comment on the matter. On June 26, 2010, Otsuka announced via a message on her official Web site that she and Su had gotten married on the previous day. Su also posted an announcement on Rip Slyme's website, confirming what Otsuka wrote on her website.
