Rachel McAdams may have played a bridesmaid in "Wedding Crashers," but that didn't stop her from tearing up during her sister's wedding!
The actress was on hand to support her younger sister, Kayleen, for her big day at the Port Cunnington Lodge in Muskoka, Canada on Saturday.
Despite a few tears, the "Aloha" star looked picture perfect in a pale blue, draped halterneck gown and gold heels as she stood next to the other bridesmaids.
The bride looked lovely in an ivory, lace gown with a sheer inlay and mermaid-style skirt, while the groom sported a light gray suit.
Kayleen works as a makeup artist in Los Angeles with stars including Sofia Vergara, Zooey Deschanel and, of course, her older sis.
Life is good for these stylish sisters!
