I don't think it's tonight, because last year it was on the following Monday and apparently it's tomorrow (Saturday) night, because there's a tweet saying cbb wrap party hosted by Chloe goodman but was just wondering

I'm sure Rylan said tonight.

Ridiculous if it is because it must start really late

In the summer they have a combined wrap party on the following Monday, but I doubt they will for this one.
It'll just be a behind the scenes party tonight.

Chloe might be hosting her own party, but it won't be an official 'wrap' party.

Why is she hosting one? She wasn't in there for long.
