Before taking the red carpet during the 2014 award season, Jennifer Lawrence played the role of celebrity bridesmaid at her brother's wedding, which is featured in the latest special issue of Martha Stewart Real Weddings. Jennifer stood with her older brother Blaine and his now-wife, Carson Massler, at the couple's wedding ceremony in Kentucky last October. The Hunger Games star left her bow, arrow, and Oscar award at home as she served as one of 11 bridesmaids during the event, looking stunning in an ivory-colored J.Crew gown.
