deos gustav had grlfriend?or who is she?

yeah, he has. i don`t know who she is..

david jost 说 that gustav has a girlfriend...

oh that's so grate
i'm so happy for u Gustav

If he has, then the band is keeping it as a secret. And that's okay with me, if he don't want to tell. but no, i'm pretty sure he doesn't?
Remember, 名人 can have 老友记 too, like everybody else ;-)

- But as i can see. @93088990 said, that he has, but does he still??

if its true i'm really happy for him :) but yes if it's true the band is keeping it a secret cause they are always saying about georg's girlfriend <3
