Brummell, Lord Alvanley, Henry Mildmay and Henry Pierrepoint were the prime movers of "Watier's", called "the Dandy Club" by Byron. They were also the four hosts of the masquerade ball in July 1813. There an event occurred which ruined Brummel. The Prince Regent greeted Alvanley and Pierrepoint, but then "cut" Brummell and Mildmay by snubbing them, staring them in the face but not speaking to them. This provoked Brummell's remark, which became famous: "Alvanley, who's your fat friend?". This widened the rift between them.
