Cameron Diaz and Diddy Play Coy at Globes Bash

Sources tell me Jay-Z and Beyonce are expected to attend, making their first public party appearance together since the baby Blue Ivy was born. Other guests like Morgan Freeman and Jamie Foxx have also been invited. I'm also told models are currently vying like crazy to work at the party, and submissions are coming from across the globe.

On the agenda for the party? Open bar and food served all night, a fashion show, and a secret performance by a Grammy nominated artist.

Businesses that chose to sponsor the event can expect prices to start at $15,000 and skyrocket up to $150,000. The party will benefit AngelWish.org.

If you are one of the chosen few to attend, be prepared for an epic evening!
