Prince William and the Duchess of Cambridge were in the crowd to watch Andy Murray go through to the finals in the Olympic tennis championship.
The couple even joined in with a Mexican wave as they watched the tennis action from the royal box alongside the president of the International Tennis Federation, Francesco Ricci Bitti.
Murray managed a comfortable win over Spain's Nicolas Almagro 6-4 6-1 and will now play in the semi-finals as he moves closer to his goal of winning Olympic gold.
"That was the goal coming into the tournament," said the Scot.
"I thought I served well today. From my side of the court I thought I was solid on serve. In the second set he was struggling and had a problem with his shoulder, so it was much easier for me to return."
Murray will now face Novak Djokovic after the Russian beat Jo-Wilfried Tsonga 6-1 6-7 on centre court. Djokovic has never lost to Murray in a grand slam so the home player will need the support of the crowd, including many enjoying London getaways, to be behind him today (August 3rd).
As if winning his singles match was not enough for Murray he also won his mixed doubles session. Alongside Laura Robson, the Scot achieved a 7-5 6-7 10-7 win over the Czech team of Radek Stepanek and Lucie Hradecka.
In the women's singles, Maria Sharapova improved her on recent Wimbledon performance where she exited the tournament in the fourth round to win against Germany's Sabine Lisicki to reach the quarter-finals of the Olympic competition. She will now face Kim Clijsters in the final eight.
Meanwhile, crowd favourite Venus Williams lost to German seventh seed and Wimbledon semi-finalist Angelique Kerber.
