Since nobody has posted anything about this yet, I thought I'd do.
I first want to say that I don't know if these are just rumors, or if it's true,
but if Yoshiki has found a girlfriend let's wish him good luck!
"Apparently the leader of the band "X Japan", Yoshiki, prefers like sentimental companion a American. The singing well-known has been seen lately with the handsome model Julia Boss.
Both walked in the red carpet during the celebration of the 50 anniversary of the prizes "Grammy" in Los Angeles, and in the concert that "X Japan" celebrated the month last in the Tokyo Dome, became to see the model supporting close by to Yoshiki. This concert was very important for the band because it was his return to the Japanese scenes.
"It is single my friend", is this Yoshiki, nevertheless, sees that its relation begins to become narrower.
Julia Boss has less than 25 years and in its work as model and actress in the United States every time gains more popularity.
On the other hand Yoshiki, that now resides in Los Angeles, has been dedicated to the composition of sound tracks for films. Its participation in the film "Saw 4", is causing that their name more and more is known in the hollywood atmosphere.
In the last visit that both did to Japan they let see in several centers of nocturnal diversion. Since then the rumors of their romance have not stopped."
