At Warwick Crown Court her barrister accused the prosecution of launching a "tabloid attack" against her.
Mrs Wadsworth and her husband Tony are on trial accused of indecently assaulting seven boys in the 1990s.
The couple deny the offences and charges of outraging public decency.
Mrs Wadsworth's barrister, David Hislop QC, criticised the prosecutions use of a "Naughty but Nice" charity calendar, in which Mrs Wadsworth posed as Lady Godiva, to suggest her career was forged "on the twang of a stocking".
He suggested the prosecution used the calendar because of "shortcomings in their evidence".
Mr Hislop claimed that prejudice and emotion had infected the investigation into allegations against the couple who previously worked for BBC Leicester and Birmingham-based BBC WM.
He stressed to the jury that Mrs Wadsworth was not on trial to assess her morals.
She accepts having sexual encounters with "young men" but denies they were underage.
The couple, from Broughton Astley in Leicestershire, are charged with five counts of outraging public decency alleging they engaged in sexual activity "against a tree" in woodland in Warwickshire in view of others between July 1992 and June 1996. They deny the charges.
Mrs Wadsworth has pleaded not guilty to 11 charges of indecent assault, while her husband denies nine counts of the same offence.
The trial continues.

Spencer White, from the Witterings area of Chichester, absconded from HMP Ford in West Sussex in July 1999.
The 39-year-old, who was convicted of kidnapping an adult, disappeared eight months into a three-year sentence.
After being recognised at Lanzarote Airport on 19 September he was stopped, detained and flown back to the UK.
At Chichester Crown Court on 23 October he admitted escaping lawful custody.
He was sentenced to 16 months, to be served on top of the two years and four months he had remaining on his original sentence.
Police believe White had been living in the Republic of Ireland and was intending to take a short break in the Canary Islands.
Sussex Police confirmed White had not been returned to HMP Ford, a jail which accommodates up to 557 inmates with less than two years left to serve.
In November 2013, police found there were a number of absconders whose cases had not been regularly reviewed.
A dedicated team was set up to review each case and in September 2014 Sussex Police said there were 83 Ford prisoners on the run.
PC Lewis Dines, from the investigation team, said: "Spencer White has been a priority to locate from the moment he absconded but he evaded immediate capture and disappeared [from] our radar.
"Within the last year we received information about his possible location and were able to secure a European Arrest Warrant so he could be arrested if found outside the UK.
"His capture and additional sentence send a message that we will not give up seeking absconders and when we put them back in front of the court they can expect further punishment."
Former BBC presenter Julie Wadsworth, accused of sex offences against under-age boys, is the victim of "poisonous and untrue" allegations, her defence claims.
