Meghan ultimately decided on a diamond and platinum bandeau tiara with Harry and the Queen, and called it "an incredibly surreal day".
The Queen reportedly warned Prince Harry over Meghan Markle's behaviour, following a row over a tiara.
"The provenance of the tiara could not be established".
The program featured a number of artists including Sir Tom Jones, Sheridan Smith, and also the Kingdom Choir, which is perhaps best known for its moving rendition of "Stand By Me" from Prince Harry and Meghan Markle's wedding in May.
It emerged yesterday that the Queen had to step in when Meghan demanded a tiara containing green emeralds, which may have come from Russian Federation.
However, when Meghan and Harry announced their engagement in November 2017, they described the moment she first met the Queen and won over her beloved corgis in their interview. She said, 'Meghan can not have whatever she wants.
To which William added: "I know, I've got serious OCD on light switches now, which is awful".
However, Meghan's decision not to wear a hat apparently caused a stir in the royal household at the time.
According to Jobson's new book, the Queen warned Harry that Markle needed to mind how she spoke to staff and to make sure she follows "family protocol".
Meanwhile, it's also been reported that Meghan and Kate Middleton, the Duchess of Cambridge, have butt heads over the treatment of staff. She has very high standards and is used to working in a Hollywood environment.
One senior figure close to the Queen said: "I don't think the duchess fully understood".
'Melissa is a hugely talented person, ' the source says.
Despite the rules, the expecting mom is "determined to do things her way", said the source.
Do you think Meghan would be hard to be around?
