The pal of the former Suits actress went on to say people shouldn't feel sorry for the 74-year-old and should instead turn their attention to the sadness the Duchess felt after her dad missed her wedding.
Let in on the secret, prison guard Christo Brand is said to have initially refused to allow Mr Mandela to see his grandchild - but eventually gave in, despite fearing he might lose his job.
Markle is no stranger to Canadian designers, as she spent some time in Toronto while filming the television show Suits.
The former lighting director (73) said he's determined to reignite contact with his daughter Meghan Markle, saying that he hasn't spoken to her since her May 19 wedding, where he pulled out of walking her up the aisle two days before.
"Glad you have so much time to gallivant around paying tribute to others while ignoring your own father!" "Enough is enough. Act like a humanitarian, act like a woman".

Samantha then defended her father Thomas after he received extreme criticism for speaking about the royals in paid interviews following the wedding.
The whole story about Meghan's father undergoing heart surgery was made up.
She later added: "My father is not an embarrassment for loving his daughter!"
He told the publication he was anxious for his daughter, saying: "I see it in her eyes, I see it in her face and I see it in her smile". My daughter said to me she would take care of me in my declining years.
Thomas Markle seemingly can't stop talking about his famous daughter, even though he said he would stop chatting with the press in his interview with The Sun that was published on Sunday. Very different from the one last week, I might add - but that's by the way.
"I see it in her eyes", he said. This is a pained smile'.
