Martin Kemp - Martin Kemp And Coleen Nolan Among U.k. Celebrity Big Brother Contestants

The Spandau Ballet bassist and The Nolans singer entered the TV house during the programme's launch on Wednesday (15Aug12).

They were joined by Jersey Shore's Mike 'The Situation' Sorrentino, So Solid Crew rapper MC Harvey and models Jasmine Lennard, Rhian Sugden and Danica Thrall, as well as former U.K. soap actresses Julie Goodyear and Cheryl Fergison.

British Olympic judo competitor Ashley MCKenzie, comic Julian Clary, journalist Samantha Brick and The Bachelor star Prince Lorenzo Borghese also entered the camera-filled house.

One famous face not in the house as planned is reality TV star Duane 'Dog' Chapman, who was denied a travel visa due to a prior murder conviction.

The stars will battle it out in a series of challenges and evictions to be crowned the winner when the show wraps next month (Sep12).
