I'm sorry, I don't know where to post this
 

I came across a video on YT 'CBBUK The Best, The Worst, The Unforgettable' and there is a past season where a blonde girl had to pretend she was in a famous girl band but she was not a celebrity at all. The short clip I saw seemed sort of funny. What season was that, and is it worth watching? Thanks in advance :)

That season is Celebrity Big Brother 4 (2006). It's definitely worth watching! It's usually considered to be the best CBB season ever.

Thank you! I will give it a go :)

Yes it’s worth watching. Not sure about best series ever but definitely the best in the C4 era, in my top 3 CBBs though. Lots of iconic moments!

Best CBB in C4.

honestly CBB3 and CBB4 are the only good C4 CBBs.
