The 36-year-old royal has been favouring pink lately and is the fifth time she's worn the colour after wearing a smart Prada skirt suit at the Queen's Young Leaders' Awards.
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.
Meghan Markle's half-sister has launched a Twitter attack on the Royal, saying: "If our father dies, I'm holding you responsible".
Meanwhile, Prince Harry, who chose a grey suit jacket and tan pants for the event, remained firmly by her side as they arrived at the Southbank Centre together, before they shared constant loving glances with each other inside.
Fresh from their dad Thomas Markle going public with claims the phone number he was given to call Meghan no longer works, and the royal contact he was assigned has shut down all communication, Samantha claims the stress is getting too much for their dad.
She added, "How about you pay tribute to your own father?!" Ndoyiya said she was happy the house would be revived and taken care of and she was hopeful it would still have the essence of a home. "Act like a humanitarian, act like a woman! Harry? I guess I was right".
They said: "The whole story about Meghan's father undergoing heart surgery was made up".
Speaking during an interview on Good Morning Britain, he admitted he hadn't been able to "get over" the furore surrounding the photos, saying: "I've got a bit of a heart condition and this pushed me a little further to the point where I had heart palpitations and I had to go to the hospital".
As The Daily Beast notes, Samantha hasn't seen her half-sister in a decade.
Samantha added, "My father is not an embarrassment for loving his daughter!"
If you don't know, Thomas spoke to the press over the weekend and said he believes his daughter is terrified of her new life as a royal.
