Jessica Alba looked stunning at the Oscars last night. In a flowing purple Marchesa gown, accented with feathers and draped empire waistline, Jessica chose a dress that hung loosely over her ever growing bump. She also selected Cartier jewels, Jimmy Choo shoes and Jimmy Choo evening purse. She revealed on the red carpet that she will be breast feeding her baby and showed off her engagement ring. Telling Ryan Seacrest: "That's really personal," but then she gave in and admitted, "yes, it's good for the baby." Jessica, who was accompanied by fiancÂŽ Cash Warren, refused to give her due date. She would only say: "I'm kind of keeping that secret." Pictures by Splash News / Russ Einhorn / Fernado Allende
