MUM-OF-11 Heather Frost could have her £60,000 per year benefits investigated after she received a four-figure fee for a recent TV appearance.
The 37-year-old receives £900-per-week in benefits for herself and eight of her children.
Ms Frost, who has never worked, is set to be investigated after receiving several thousands of pounds for appearing on the Channel 5 show On Benefits and Proud.
The TV station would not comment about the payment but it is said to be worth up to £6,000.
Richard Horton, Tewkesbury Borough Council's revenues and benefits group manager, said: "In all cases if we believe there are grounds for an investigation then we are duty bound to carry one out."
He said that he could not discuss Ms Frost's benefits.
Robert Oxley, campaign director of the TaxPayers' Alliance, said: "Life on welfare shouldn't be an alternative to finding genuine work.
"Claimants have a duty to declare if their circumstances change as benefits are a safety net, not an alternative form of income.
"Taxpayers footing the bill will take a dim view of someone still claiming every penny they can while sitting on a handsome cheque for thousands."
When asked about her benefits bonanza, Ms Frost said: "Yes people don't agree with the benefits system but it is put there to help people who can't go to work."
The investigation comes as Severn Vale Housing make £2,000 of improvements on her Innsworth Lane home.
She had been due to move into a £500,000 new build in Tewkesbury in August, but an 11th hour U-turn by the housing provider decided the home was not suitable.
Instead Ms Frost and her large brood will remain at her current property, which is made up of two houses that have been knocked together.
Claudia Cobban, housing manager at Severn Vale Housing, said: "We are planning to carry out minimal changes to the Frost's current home to make it more suitable for the family's needs.
"The changes will improve the connection been the two properties, providing a more permanent solution for the family."
Ms Frost was recently investigated by police under caution when it was suggested that she had been buying stolen goods on the doorstep. That investigation is still ongoing, police have said.
Ms Frost declined to comment when contacted by the Echo.
