A royal expert says Prince Charles' nickname for his daughter-in-law Meghan Markle reveals his true feelings about her.
The Prince of Wales reportedly refers to Meghan as "Tungsten", which he means as a compliment, the expert has said.
In this context, tungsten is intended to describe someone who is toughened and resilient.
"Meghan Markle hasn't had an easy time of it since joining the royal family," royal expert Christine-Marie Liwag Dixon explained on The List.
