Prince William and Princess Kate have revealed their most used emojis

While on a visit to Birmingham for World Mental Health Day, Kate and William spoke to BBC Radio 1 and revealed what emoji takes the crown for the pair.

"Is this a clean thing, or is this a family one?" William asked before giving his answer.

"I've been told not to say the aubergine, so I've got to pick something else. It would've been the aubergine, but I'm saying now—because I've got to be a little grown-up—it's the one where the eyes go up and down and the mouth's out."

Kate went for a more PG answer, "Mine's probably going to be the heart, with then the crying emoji— the sort of like hysterical laughing when things have gone wrong."

BBC Radio 1's hosts Vick Hope and Jordan North couldn't get enough of William's answer, "He said the aubergine emoji! What is happening? He said the aubergine emoji! This is brilliant."

William and Kate also spoke to the pair about their dinner plans and their differing spice-tolerance levels. 

"I can't do too much spice. I start sweating," William shared "It's unattractive."

As for Kate, she shared, "I like the spice. I have to sort of cook the curry and then add the spice—extra spice—at the end."

William added, "She has to bring it in gently because otherwise I get too sweaty. It's not a nice sight."
