The Duke and Duchess of Cambridge arrived at Wimbledon today to watch Andy Murray battle for a place in the semi-finals.
William and Kate were warmly applauded by the Centre Court crowd as they took their places in the Royal Box to see Britain's top tennis star in action against big server Vasek Pospisil.
The Duchess, wearing a bright red dress, and the Duke were joined in the Royal Box by adventurer Bear Grylls, former Olympic rower Sir Matthew Pinsent and Britain's greatest female distance runner Paula Radcliffe.
Prince Albert II of Monaco, the Countess of Wessex and Prince Michael of Kent were among the royal guests on Centre Court.
David Beckham, wearing a blue blazer and white shirt, was also in the crowd with his son Romeo.
The former England footballer hugged Murray's mother Judy as she took her seat in front of them, before Romeo shook her hand.
Murray, 28, who is the third seed, will be hoping to exploit any signs of tiredness from Canadian Pospisil in their quarter-finals tie.
His 25-year-old opponent played two five-set matches on Monday including a doubles defeat to Andy's older brother Jamie.
William and Kate stood and clapped as Murray walked on to court as he continues his quest for a second Wimbledon title.
Rain disrupted play at Wimbledon shortly after the start of Murray's match.
There was a touch of Hollywood stardom in SW19, with actor Josh Hartnett in the Royal Box and The Hangover star Bradley Cooper on No 1 Court in Roger Federer's box.
Spectators leaving late in the day could face difficulties as London Underground workers go on strike.
Transport for London has advised travellers to complete their Tube journeys by 5pm, with the strike due to last until tomorrow evening and disruptions possibly extending into Friday morning.
Tubes are expected to be "exceptionally busy" between 4pm and 6pm today as people try to get home before the 24-hour strike officially starts at 6.30pm.
William and Kate both shielded their eyes with pairs of sunglasses during the match before another shower brought Murray's match to a halt, with the Scot one set up.
During the break, former Manchester United star Beckham was seen chatting with current player Ashley Young.
Kate's parents Carole and Michael Middleton were also photographed arriving at the All England Club earlier.
The last time a senior royal watched Murray at Wimbledon, he threw a sweaty wristband in celebration towards the Duchess of Cornwall after his second round win.
A royal source confirmed later that Camilla was "delighted" with her memento and she had kept it in her handbag.
