The DNC is keeping some of the guests and timings secret to create suspense before President Barack Obama formally accepts the party's nomination.
Former House Rep. Gabrielle Giffords will start off the official opening tonight with the Pledge of Allegiance. A number of Hollywood celebrities including Desperate Housewives star Eva Longoria will make appearances tonight according to a CNN report.
The "mystery guests" appear to all be Hollywood women: Scarlett Johansson, Natalie Portman and Kerry Washington. This will create an interesting contrast to the RNC's selection of Clint Eastwood. Caroline Kennedy may also speak tonight.
