Jessica Alba rocked jeans and a black blazer while out running errands in Beverly Hills yesterday afternoon, but she changed into a long, white Dolce & Gabanna gown by the evening to attend the annual Covenant House gala and dinner. She mingled with two of her favorite people, director James Cameron and his wife Suzy Amis, at the philanthropic event, which raised funds to support the charity's work with homeless youth. Jessica even presented James and Suzy with a special award to recognize their activism on behalf of the organization. The night of good deeds was Jessica's latest red carpet event after she attended the CFDA Awards in NYC on Monday night. A less formal, but possibly more important event happened for Jessica on Tuesday, when she and her husband Cash Warren celebrated their daughter Honor's third birthday.
