Danniella Westbrook (born 5 November 1973) is an English actress and television presenter. She is known for being the original actress to play Sam Mitchell in EastEnders from 1990–93, 1995–96, 1999–2000 and 2009–10. Away from EastEnders she has presented various shows, and was also a contestant on ITV's I'm a Celebrity... Get Me Out of Here! in 2003. Westbrook returned to filming for EastEnders as Sam Mitchell in June 2009 and left when the character was sent to prison in January 2010. However, Westbrook returned to the programme in Summer 2010 for a handful of episodes. She competed in the 2010 series of Dancing on Ice with US Pairs Skater Matthew Gonzalez and finished fourth in the competition.

Westbrook struggled with a much publicised cocaine addiction throughout the 1990s and early 2000s, which caused the complete erosion of her nasal septum/colonna. She sought treatment and no longer uses drugs. She is married with two children, and released her autobiography, The Other Side of Nowhere, in 2006.
