They're clearly madly in love but experts have noted that the Duke and Duchess of Cambridge rarely hold hands in public - and there's a very surprising reason why.
Robin Kermode, body language expert and founder of communications coaching company Zone2.co.uk, explains, Kate and William, who married in 2011, are taking cues from the Queen, according to Daily Mail.
"The Queen rarely holds hands with her husband in public and this seems to have set an unwritten precedent for the other royals, notes Robin.
"It is very clear that William and Kate are emotionally close, however, they do not seem to feel the need to prove their love - particularly when on official state business.'
