The Extremely Loud and Incredibly Close actress, 38, sparkled on the red carpet at the Dolby Theatre in a gorgeous, fully embroidered cap-sleeve gown by Elie Saab, complemented by Harry Winston jewels -- including a piece or two selected by her little boy. According to the insider, Louis singled out the baubles while playing around at one of Bullock's dress-fittings with her stylist.

"Sandra really wanted to wear the rings her son picked for her," the source tells Us of the star, who has been a doting mother ever since adopting Louis in 2010. (Bullock originally planned to adopt the tot with ex-husband Jesse James but changed her plans when the couple split following James' infidelity.)
