Career: Kemp has rarely been out of work since graduating in 1985. His first credited TV appearance was in Emmerdale in 1986. He also appeared in a string of Kellogg's adverts and featured in such series as Birds of a Feather and London's Burning, before landing the role of Grant in EastEnders - the part that made him a household name. He left in 1999 after nine years. He then appeared in A Christmas Carol, Ultimate Force, In Defence, Hero of the Hour, A Line in the Sand, and a TV remake of Spartacus. In 2005, he featured in an episode of Extras and made a brief, but much-publicised return to EastEnders. He has also hosted a number of hard-hitting documentaries for Sky1, including the Bafta-winning Ross Kemp on Gangs.

Career: Sinitta released her first single, Never Too Late, in 1983.

Her debut self-titled album was released a year later and it included the hits Toy Boy, GTO, Cross My Broken Heart and Right Back Where We Started From. The album only peaked at number 34 and her music career soon began to fade away. Her stage credits include The Wiz, Cats, Little Shop of Horrors, Hair and Mutiny!

In 2010, she appeared as a contestant on Dancing on Ice, and a year later, she entered the jungle in I'm a Celebrity… Get Me Out of Here!
