David and Victoria Beckham have been pictured together on the 1,000 sq ft private beach they are accused of failing to mention in an application for their £12million Cotswolds home.
An investigation was launched into the celebrity couple by West Oxfordshire officers over the sprawling sand bank - after neighbours saw it on TV.
In the new Netflix series, Victoria Beckham, the former Spice Girl and her husband showed off the man-made beach on their 43-acre estate, attracting the attention of the district council.
Bordering a large artificial lake, the beach was visible between a wooden jetty and a safari tent as the couple sat tearfully discussing Victoria's ambitions and their future together.
Yet when the kidney-shaped lake was installed, the rules were extremely specific to ensure it would 'sit well in its rural context'.
Detailed notes and diagrams at the time said the surrounding area should be landscaped like an 'organic parkland', with wildflower meadows and native trees, and scrub and other plants to provide a habitat for nesting birds, small animals and insects.
David and Victoria were filmed looking out at their private sandbank as they reflected on its beauty.
The council is now investigating concerns the beach is not consistent with what was agreed.

A source told The Sun: 'Neighbours think it is totally out of character for the surrounding area and they are very twitchy around adhering to the rules.'
The safari tent near the beach was made by a firm owned by the couple's mogul friend, Guy Ritchie.
The film director was once ordered to remove similar tents around lake at Ashcombe House in Wiltshire after they were spotted in a trailer for his Netflix series Gentlemen.
West Oxfordshire District Council confirmed: 'A report of a planning breach has been received and will now be investigated.'
The Beckhams did not respond to a request for comment.
Last week it was revealed David had created his own oasis of peace in his Cotswolds garden.
The plot, which cost him tens if not hundreds of thousands of pounds, was shown in all its glory with radishes, carrots, kale and onions to name just a few.
Chickens and bees, as well as roses for Victoria and 14-year-old daughter Harper were also visible.

Sir David, 50, credited his maternal grandfather, Joe, with passing on his green fingers.
It comes as the former Manchester United star's parents, Ted and Sandra, were never really into gardening.
He told the Daily Mail: 'Grandad Joe would come to our house every Sunday to tend to the roses and, when he left, it would all look perfect.
'Then he'd visit the Sunday after, only to find that all the heads had been knocked off the roses because I'd been kicking a football around.
'As much as he loved me, I think that drove him mad!
'Although I didn't really plant anything with him, I showed an interest and he talked me through everything he was doing, so I think that's where my love of gardening came from, even if I didn't realise it at the time.'
