Here's what went down in celebrityville while we ate hot dogs this Memorial Day Weekend:
*Snooki was involved in a fender bender on Monday in Florence when she crashed into a police car driven by an escort hired for her personal safety. The "Jersey Shore" tanning enthusiast and scholar filed an accident report, but refused medical treatment. Back to the beach!
*Sad news: Singer Sean Kingston remains in critical condition following a jet ski accident in Miami on Sunday morning. Contrary to reports, there was no alcohol in his system.
*Adrianne Curry and Christopher Knight announced their separation after five years of marriage. Why are we sad about this?
*An inconsolable Cheryl Cole refused to renew her gig on Britain's "X Factor" after being unceremoniously dumped by Simon Cowell for the American edition. Cole's replacement: Kelly Rowland.
*A-listers flocked to producer Joel Silver's Memorial Day bash. Among the guests: Tom Cruise, Katie Holmes, Courteney Cox, David Arquette, Sylvester Stallone, Barbra Streisand, RDJ, Guy Ritchie and mommy-to-be January Jones, who's involved in some baby daddy drama with Ritchie's best friend, "X-Men" director Matthew Vaughn.
