Looking ever so smart, and rather happy, Spenny joined former co-star Hugo at the event, which was held at Windsor Great Park.
Spencer was without girlfriend Lauren Frazer Hutton, but that didn't stop him from enjoying the day's festivities with his pals.
While Spencer is still home in the UK, some of his co-stars have already jetted off to Los Angeles ahead of the new spin-off series of the E4 reality show.
The cast will soon be filming around Beverley Hills' most stylish locations, where they'll be probably shopping, hanging out at beaches and partying on Sunset Boulevard...basically living the life!
Made In Chelsea: LA will feature six hour-long episodes and will air on E4 this summer, but in the meantime, fans can continue to watch the current series tonight, which marks iMIC's 100th episode.
The cast will be doing an E4 takeover from 8pm, which will be filled with shows including a Rick Edwards 100th episode special, Virtually Famous: Chelsea Takeover and a special Come Dine With Me.
