I know someone who got through to the second round of auditions for BB4. I've been tempted to apply since BB2, but my lack of video camera makes me fall at the first hurdle. And I have to admit, I hate the way E4 screen all the submitted videos anyway. If I were to get on BB, I'd have no problem with people seeing me make a prat of myself on my audition tape, but if I don't, I don't want it screened!
