Born in Swindon, Wiltshire, in 1967, Lamarr began performing stand up at London's Comedy Store in the mid 1980s.
He hosted Never Mind the Bollocks between 1996 and 2005.
Lamarr became famous in the 1990s for presenting shows such as Channel 4's The Big Breakfast, and The Word with Terry Christian.
Lamarr was also a team captain on Reeves and Mortimer's panel show Shooting Stars, where he was relentlessly mocked for being a "Fifties throwback".
Comedian Mark Lamarr has been charged with assaulting and holding prisoner a woman believed to be an ex.
Other radio stations has worked for include BBC Radio 1, BBC Radio 5 and GLR.
News reports have quoted a neighbour as saying the ex TV star keeps a low profile but is often seen "pottering around vehicle boot sales". He will appear before magistrates in Uxbridge, London on October 2, the police said.
