I'd say its arguably 7

I'd say 15, even though it did have some 'who' celebrities like Chloe and Cami-Li. It did have a lot of celebrities that are quite well known e.g. Alexander O'Neal, Katie Price, Perez Hilton, Nadia Sawalha, Michelle Visage.

I think cbb15 overall has the most infamous people. Everyone knows who the katie’s, Perez and Michelle visage are. Overall Kirstie and Jermaine are probably the most famous people that we’ve ever had on this show, and oddly enough they both lost out to the sympathy vote in the final following a controversial incident :skull:

I just went on the names listed and was undecided between 4,5 and 7. Went for 4.
To me, Kirstie Alley was the most famous celeb of them all.

15 probably. Only unknowns were Cami & Chlo (and Alicia to an extent). Hopkins was huge back then and Perez/Pricey/Patsy are all really well known.

Well 18 had the world famous Bear!

15 or 21, i only didn't know Jess , Rachel and John from 21, but then there was a lot of reality tv people (Ashley, Malika, Jonny, Andrew) who I knew of but the general public might not

15 though 4 and 7 also have pretty well-known line-ups...

6, 7 and 13 had current relevant music stars as well as other big names who've been around for a while (Evander holyfield, stephanie beacham etc)
