Kevin Spacey, Rolling Stones frontman Mick Jagger, newly single Simon Cowell and Lily Allen were all in attendance.

Also on hand was Sting's wife Trudie Styler, 54, who was snapped chatting up Guy Ritchie, 40.

Sting and Trudie famously introduced Ritchie to future wife Madonna in the late '90s. A decade later, the Material Girl, 50, and the Sherlock Holmes director are now in the final stages of their divorce.

Rumors persist that Madge and her current fling—New York Yankees third baseman Alex Rodriguez, 33—are looking to settle down in a Manhattan home together.
