Coolio was the "best value for money" bigger name they've ever had in there... absolute gold.

There has never been an A-list celebrity in the house. Mainly Z's and D's, a couple of C's and maybe an ex B or two... but nothing close to A-list.

There are hardly any UK singers who qualify as A-list... let alone a member of a dead girl band. The "biggest name" from Girls Aloud is Cheryl and she is barely scraping the bottom of the B-list barrel.

I think they seem to like to just skip over the whole concept of B and C though... you're either Z, D or suddenly A in Big Brother world.

In reality... an A-list star, you're looking at the PROPER big leagues... people CURRENTLY pulling in massive Box Office figures or huge on the "world stage"... e.g. Will Smith, Leonardo DiCaprio, Tom Hanks, Brad Pitt... etc. or your older relics like Arnie, Sly Stallone (not Jackie... haha), Harrison Ford, Robert DeNiro, people who might not be particularly active now but were HUGE in their day.

Lindsay Lohan being invited along to a party with these guys? ... Really? Maybe as some sort of circus act where they load her up with vodka and cocaine for giggles but that's about it. Lindsay Lohan is not an A-list celebrity. She's currently hovering around C and was never above B.
