The pair had dated from 2003 to 2010, with their final split coming in 2011. Angela Levin, author of royal biography ‘Harry: Conversations with the Prince’, detailed how the separated Harry and Ms Davy had a conversation about the Prince’s “racier” jokes in his speech. While the Sussex royal and the Zimbabwean lawyer were not in a relationship at the time, she was invited to the ceremony because of their close friendship.
In her book, Ms Levin claims Harry called Ms Davy about what he would say during his speech as best man.
But Ms Davy urged Harry to axe some of the more mature jokes as to not upset Queen Elizabeth II.
She said: “Harry had read it out at first over the phone to Chelsy in South Africa, who despite no longer being his steady girlfriend, has also been invited to the wedding.
“She suggested he remove some of the racier anecdotes, including a reference to Kate’s ‘killer legs’, as she didn’t think the Queen would take kindly to laddish humour.”

While the Prince listened, attendees at the Cambridge wedding reception told the Mail on Sunday Harry still cracked jokes.
A party goer told the outlet Harry said: “William didn’t have a romantic bone in his body before he met Kate, so I knew
it was serious when William suddenly started cooing down the phone at Kate.”
They also said of the Duke of Sussex: “It was exactly how you would expect a best man’s speech to be.
“He cracked loads of jokes about William. He called him a ‘dude’ several times.
“He kept coming back to it, saying ‘What a dude.’”
But Robert Lacey, royal expert and author of ‘Battle of Brothers’ explained Ms Davy saw a glimpse of the pressures of royal life in Kate and William’s marriage and was “uncomfortable”.
He said the wedding caused Harry and Ms Davy to have a conversation about their relationship, with the pair agreeing to split for good in the wake of the ceremony.
Mr Lacey said: “In 2011, after more comings and goings, she finally decided to go – and it was, ironically, Kate and William’s grand and glorious wedding that spring that did it for her.
“According to a friend, she told Harry that she could never make the scarifies she had witnessed Kate making, particularly when it came to moulding her life around the unremitting attention of the press.”
Ms Levin also detailed in her book how Harry’s former lover struggled with the Cambridge wedding.
She said: “A friend revealed that seeing the enormity and pomp of the day convinced Chelsy that she and Harry had been right to separate.
“Although they had a lot in common, she saw clearly that because they came from such different worlds it could never have worked, especially as she valued her privacy and guarded it so carefully.”
Harry and Ms Davy remain friends, with the Zimbabwean lawyer making an appearance at the Duke’s wedding to Meghan Markle in 2018.
