Queen Elizabeth II arrives at Kensington Palace
One of the first guests to arrive was one of George's four godfathers, Jamie Lowther-Pinkerton, the former principal private secretary of Prince William and the Duchess, née Kate Middleton, who had a present in the front seat of his car.
The one-year-old has seven godparents in total of all whom have been invited.
The adorable little Prince's great-grandmother Queen Elizabeth II arrived just after 4pm. As expected, the Queen arrived solo, as the Duke of Edinburgh had previous engagements he had to attend.
His uncle Prince Harry was also in attendance, along with Prince and Princess Michael of Kent.
Zara and Mike Tindall arrive at Kensington Palace
Zara Tindall, one of George's godmothers, also arrived with her husband Mike Tindall and baby daughter Mia Tindall.
