The Duke and Duchess of Cambridge will cheer on Andy Murray at his quarter-final clash at Wimbledon today.
William and Kate will take their seats in the Royal Box on Centre Court alongside Princess Beatrice, actor Hugh Grant, comedian Michael McIntyre and England rugby union coach Stuart Lancaster.
Australian teenager Nick Kyrgios is also back on court today after beating world number one Rafael Nadal in a match even his own mother thought he would lose.
The 19-year-old produced one of the greatest shocks in the tournament's history by defeating the Spaniard in four sets last night.
When Murray takes on Grigor Dimitrov in the second match on Centre Court today there will be plenty of interest in the action in the stands.
Murray's long-term girlfriend Kim Sears usually grabs the attention in the players' box as she cuts a stern figure during the Scot's matches.
But she could be forced to share the spotlight with the glamorous Maria Sharapova, if she decides to cheer on her boyfriend Dimitrov.
