Here's a look at the Celebrity Big Brother 2013 line up of housemates... before they entered!
All looking rather glam in their hotel rooms before they entered the house this evening, the latest celeb lineup is one of the most diverse yet.
For the second year in a row, there's an X Factor reject in the form of Rylan Clark, while Lacey Banghard provides the token model housemate.
There's no fewer than four soap stars, with Ryan Moloney, Gillian Taylforth, Sam Robertson and Tricia Penrose all in the house.
They are all joined by US reality stars Heidi Montag and Spencer Pratt, jockey Frankie Dettorri, mode Paula Hamilton and Steps singer Claire Richards.
Footie star turned telly personality Neil 'Razor' Ruddock completes the line up, having replaced comic Jim Davidson.
