Prince Charles and Princess Diana got engaged in 1981. Diana was 19 and Charles was 32.
They had only met each other 13 times when Prince Charles proposed.
During their engagement interview, Prince Charles and Princess Diana showed different facial expressions, body language expert Robin Kermode told The Express. "Charles looks assured while Diana often looks sadder when she is listening — her lips and mouth are held together, here eyebrows lifted and her cheeks pushed forward with watery eyes."
Kermode pointed out another interesting moment during the interview. When the interviewer asks Charles about the proposal, "Diana smiles, pulling her lips up and forward indicating she expected the engagement. This becomes almost a wry smile as if to say, 'I wonder if he will tell the actual story here.' Then as Charles continues to speak, her look changes — her lip corners are pulled right down and tight, her jaw is pushed forward and she takes her eyes away from him."

Body language expert Darren Stanton observed to The Independent that, while Markle sometimes seemed more confident than Harry, she glanced at him after answering a question to make sure he was happy with her response.
Stanton also noted that Prince Harry and Markle held hands throughout the entire interview, and made prolonged eye contact. Stanton said, "It's clear from that gesture alone the two are truly in love and besotted with each other."
