Betting money, quaffing champagne and cheering on horses - it was all systems go when Spencer and co-stars Binky Felstead and Ollie Locke enjoyed an afternoon at the world-famous racing site.
And it wasn't just any celebrity event, as Her Majesty The Queen attended the QIPCO British Champions Day.
Also in The Queen's attendance was her granddaughter Princess Beatrice, former Reveal columnist Katie Piper and Geordie favourites Ant and Dec.
All the star guests were suited and booted, with the men in shirts and ties and the ladies in dresses, as they watched wonderhorse Frankel maintain his unbeaten record by winning the QIPCO Champions Stakes - securing his 14th straight victory.
Meanwhile, in true Chelsea fashion, Spencer, Binky and Ollie were living it up, smiling with fans as they enjoyed a flutter on the fillies.
Tweeting after the event at Ascot, MIC favourite Binky wrote: ''SUCH an amazing day at the races! Real honour to be here. Now waiting for traffic to flow whilst sipping on more bloody Marys!''
We wish we could've joined you!
