Hai lovely, I just saw you asking Raph if he knew links for Big Brother UK, yes they are usually uploaded to youtube, or you can check...

Not sure how reliable they can be though, or if you wanted to watch it live, it starts at 9pm (so just under 90 minutes) over here and you can just type 'CHANNEL 5 LIVE STREAM' into google, and it should come up with a link as well. Hope I've helped
