The estranged wife, from East Sussex, of paralysed former motorbike stunt rider Eddie Kidd has pleaded guilty to assaulting him - days before she was due to stand trial.
Samantha Kidd, 44, pleaded not guilty in January to claims she beat the 54-year-old wheelchair-bound star over a four-month period, and a two-day trial was set to start next Tuesday.
But at a pre-trial hearing at Brighton Magistrates’ Court, Kidd admitted four counts of assault by beating between July and October last year, Sussex Police said.
Unemployed Kidd, of High Street, Seaford, was released on bail and she will be sentenced on August 1.
Mr Kidd - who was paralysed and brain-damaged when a stunt went wrong in August 1996 - received an OBE last year for services to charitable giving.
He carried the Olympic torch through Lewes on July 17 last year after being selected for walking the 2011 London Marathon in 50 days and raising more than £100,000.
