Olympic champion Sir Mo Farrah joined stars from the worlds of sport and television for a day at Royal Ascot.
The long distance runner - who won four Olympic golds - looked smart in a top hat and tails as he, wife Tania and thousands of spectators enjoyed the famous Berkshire race course.
Sir Mo, who presented the prizes for the first race, the Queen Mary Stakes, said as the day started: "I'm just here to enjoy the racing, I haven't been here before but I'm looking forward to it."
Other famous faces who took their places track-side included TV presenter Declan Donnelly and his pregnant wife Ali, football pundit Robbie Savage and sports presenter Kirsty Gallacher.
Talk Show host and race horse owner Jeremy Kyle, said: "I love Ascot, it's a good day out but it's different. It's all about the social aspect."
The traditional betting on the colour of the Queen's hat had seen blue become the runaway favourite with many bookmakers.
So when the Queen arrived at the head of the carriage procession wearing a powder-blue outfit, the bookies were left paying out for the second day running after she wore a heavily backed yellow hat on Tuesday.
The Stewart Parvin ensemble included an A-line coat, a floral silk dress in shades of pink, powder blue and taupe with a matching hat by Rachel Trevor-Morgan.
Coral spokesman Harry Aitkenhead said: "It's left us feeling a little blue and perhaps the Queen will be looking to back Shades Of Blue or maybe even Come On Leicester in the first race if blue is to be the colour today at Ascot."
William Hill spokesman Rupert Adams said: "That is two days in a row that we have had a hat horror show, in fact we have had to pay out on both blue and purple after a number of queries."
The Prince of Wales and Duchess of Cornwall joined the Queen in the royal box and presented the winning prizes in the aptly named Prince of Wales's Stakes, while the Earl of Wessex performed the same role in the Duke of Cambridge Stakes.
Later in the day the Queen's horse Seniority was well beaten in the Royal Hunt Cup.
