Mike Tindall blasted Prince Harry during the Queen's Platinum Jubilee celebrations.
A source overheard the former English rugby player saying that the Duke of Sussex's behaviour was that of a "b***end".
He made the comment to a fellow guest at a reception held after the televised Platinum Party concert at Buckingham Palace on June 4, the Daily Express reports.
Prince Harry and Meghan Markle only attended one jubilee event, which was a thanksgiving service held the day before the concert.
Footage which was broadcast of the event showed Prince Harry and Meghan Markle approach Mr Tindall and his wife Zara, the Queen's granddaughter, following the ceremony on June 3.
Mr Tindall appeared to visibly avoid speaking to the Duke and Duchess of Sussex by staring into the distance and then speaking to other royals.
Speaking about the clip, body language expert Judi James told the Express : “With Mike’s closeness to William in mind it also appeared to have created a bit of a dilemma as Harry stepped out into Zara’s group as they waited for their transport.
"Zara looks happy to chat and even turns fully to talk to Harry here, who is looking anxious and keen to get into his own car.
“Mike though remains facing forward, looking about and holding his order of service up with a look of awkwardness.
"In the end he talks to Viscount Lindley, who turns his own back on Harry, cutting the two men off from Zara’s conversation with Harry.
“This doesn’t appear to be Mike’s normal style of behaviour as he usually looks too easy-going and too tough to get involved in politics and it could be that his attention was taken arranging the right cars, but there are no signs of any farewell from him, either.”
Mr Tindall has been approached for comment.
Discussing the Platinum Party, Mr Tindall previously told The Good, The Bad, and The Rugby podcast: "It was at the concert where there was a bit more of a chat together because we went in and had a drink with everyone after.
“I think the committee that put it together did an incredible job.”
