Prince William has been caught on camera giving his wife Duchess Catherine a kiss!
The couple, who are notoriously private when it comes to public displays of affection, were showing their support for runners of the 2017 London marathon.
William was photographed putting on a rare show of affection towards his wife, leaning in to kiss the side of her head as she giggled shyly.
Prince Harry also joined the married couple at the event.
The trio pressed a large red button to signal the start of the race.
The Duke and Duchess of Cambridge gave a rare insight into their married life during an interview on BB1 Radio.
When host Scott Mills asked about their day-to-day life, Wills and Kate gave some very candid answers - revealing they enjoy ordering their favourite takeaway curry while lounging in their comfortable clothes watching Homeland or Game of Thrones at Kensington Palace.
On the subject of music, William spilled thaat he and Kate had partied with Tinie Tempah at Radio 1's Big Weekend in Bangor and even joked about his notorious 'dad dancing' in Verbier earlier this year when he admitted the couple would love to go to Glastonbury but haven't yet managed it.
'I've got into enough trouble with my dancing recently. So it's probably best to stay away from that one,' he said.
Once the children are in bed, the pair often like to relax with a box set, naming Homeland and Game of Thrones as their go-to shows.
'So do you ever order takeaways? What’s your favourite?' Scott asked.
'Absolutely and curry - definitely!' Kate admitted.
However, the royals don’t actually get the food delivered to the palace doors, with William confessing: 'It doesn’t usually get ordered to the Palace to be honest, normally someone goes and picks it up.'
Scott was eager to find out what the royals wear during the nights they stay in to relax and asked if they wear jogging bottoms.
William replied: 'I’ve got my comfy clothes, yes. I don’t know if they're the same as what you wear though.'
