The 59-year-old looked fuming as security appeared to shepherd him away from St George’s Chapel in Windsor, Berkshire, as he tried to waltz in wearing a dapper beige suit.
Footage swooping over thousands of fans captured the Princess of Wales’s former housekeeper in what looked like a heated chat with security in orange hi vis vests as he approached the entrance with a male pal in shades.
Mr Burrell was then captured being ushered off by a stern security guard who held an arm out to stop Mr Burrell walking past.
Mr Burrell said in an interview just yesterday that the “spirit” of Diana, who died in a Paris car crash aged 36, is at Windsor in the run-up to her son Prince Harry’s nuptials to his American fiancé Meghan Markle today.

Speaking on ITV’s Lorraine show at the famous Long Walk, he told cameras he had brought gifts from Diana, to make her presence felt in the run up to the special day.
He said: “Well she will be here in spirit, Lorraine.
“She’s here with me today in this beautiful sunshine on the Long Walk.
“I’m wearing the links that she gave me – very special links.
“I’m wearing a tie that she gave me to go to Egypt, and of course a white rose which is symbolic of Diana.”

He added: “Watch out for those white roses at this wedding. There will be little hints of Diana all the way through it.”
Mr Burrell served Diana for a decade from 1987 to her untimely death in 1997.
He infamously told Channel 5 horrific details of the crash, including Diana's "soft, warm corpse".
He claimed in a kiss-and-tell book about the icon and national treasure that Diana called him “the only man she ever trusted” though there has been no evidence other than his own writing to support this statement.
But after flogging some of her most personal possessions, two-decades of tell-all revelations and appearing on reality TV programme Celebrity Big Brother, he was blacklisted by the royal family.
Last year, the divorce and father-of-two came out as gay publicly and announced he planned to marry partner Graham Cooper, who also served as his lawyer.
The couple tied the knot last April.
