Watch (above) to get the scoop and then help us share the exciting news!!!!
The actress HIGHlighted her fiery red locks with a cherry red Prada gown with jeweled neckline and bow at the back.
Because she didn't need a necklace, Jessica opted for a gorgeous Harry Winston diamond, and ruby bracelet, and teardrop ruby earrings.
Compared to some of her past looks, we aren't blown away, but we have a feeling she'll more than make up for it on Sunday.
