Blake Lively Steals The Show At Chanel Jewelry's 80th Anniversary Party

Blake Lively attended Chanel Fine Jewelry's 80th anniversary celebration of the Bijoux De Diamants collection, and she looked stunning when she posed for pictures at the party. For a moment the Gossip Girl hottie took her hands out of the pockets of her satin dress, and we got a peek at her massive Lorraine Schwartz pink diamond engagement ring. Hubby Ryan Reynolds sure knows how to pick 'em!

Blake and Ryan tied the knot in a small ceremony in Mount Pleasant, South Carolina last month, and it was recently revealed that she wore a Marchesa gown when she walked down the aisle. Blake is still an ambassador for Chanel, so hopefully Karl Lagerfeld and company aren't too offended!

January Jones, Rose Byrne, Alexa Chung, Elle Fanning and Diane Kruger were among the lovely ladies who also attended the event ... click the gallery below for more photos!
