Two of the best known yuri seiyuu couples have posted rather romantic New Year's photos on their blogs (all four of them): Sanpei Yuuko 三瓶由布子 and Koshimizu Ami 小清水亜美 , and Nabatame Hitomi
生天目仁美 ,and Itou Shizuka 伊藤静.
Sanpei Yuuko's pic of Amisuke (right) says : "Happy New Year 2009" and "badump" (
dokki, the sound of a heartbeat). Amisuke's pic of Yuuyu (whom she alone calls "Pe"), just says "Happy New Year."

Itou Shizuka posted a pic of her wedding with Nabatame Hitomi. And Naba-sama posted a pic of Shizuka-sama waking up to 2009 (she added with unnecessary honesty that in fact it wasn't taken then). Lovely.

Thanks to NKDS for posting a complete magazine spread on the wedding, which is supposed to come out on disk -- something which makes it seem that this is mainly a publicity stunt, rather than a romance, even if the two do like each other a lot.

Click the pic to enlarge. In the group shot below, I recognize Amisuke and Shimizu Kaori behind the groom (Naba-sama), and I think that's the recently married (to a guy) Inokuchi Yuka to the groom's left, Satou Rina second from the far right, and Itou Miki second from the far left.

More of the faces look familiar, but I can't put names to them. Can anyone else?
Naba-sama (32) and Shizuka-sama (28) are the best-known seiyuu couple. They constantly make jokes about it. But I really don't know how serious this "yuri seiyuu" thing is. They all have separate outings with other seiyuu. However, I did notice that Amisuke (22) mentioned having tea with Pe (22) "late at night," and in another post was helping her redo her room.
