The sweet nickname Prince Charles has given Meghan Markle.

He walked her down the aisle, so it’s perhaps no surprise Prince Charles has his own nickname for his daughter-in-law the Duchess of Sussex.

The Mail on Sunday reports Prince Charles calls the Duchess of Sussex Tungsten because she is as strong as metal.

“Prince Charles admires Meghan for her strength and the backbone she gives Harry, who needs a tungsten-type figure in his life as he can be a bit of a softie. It’s become a term of endearment,” a source told the paper.

Last month, the Duchess walked herself partly down the aisle of St George’s Chapel, walking only with a few bridesmaids and pageboys as a senior church figure led the way.

Prince Charles then stepped in and escorted her once she reached the Quire and accompanied her to the altar.

The strong bond between the two was made public after the Duchess’ father, Thomas Markle, was forced to pull out of the royal wedding on account of heart issues in the lead up up to the wedding.
