When picking bridesmaids, brides-to-be usually consider a few questions. Who are my closest friends? Who has supported me through thick and thin, especially in my relationship with my fiancé? And finally, which friends do I want standing next to me on the biggest day of my life? For bride Christine Quinn, the person who checked each of these boxes is her best friend . . . who also happens to be her 89-year-old grandmother, Nana Betty.

"While she doesn't live that close, we have continually made it a point to spend as much time together as possible," Quinn told the Huffington Post [1] of her special bond with Nana Betty. "She just has an amazing sense of humor and outlook on life that I strive to emulate every day. Everyone loves her." While it's a little out of the ordinary, it was the obvious choice for Nana Betty to serve as one of her granddaughter's bridesmaids.

"Nana Betty could keep up with the non-stop shenanigans (read non-stop laughter)," wrote wedding photographer Sweetwater Portraits [2] in a blog post about the big day. Betty, who wore the same dusty-purple gown as the rest of Quinn's bridal party, positively glowed with joy during the festivities — and she kept the celebrations raging into the night. "Nana got on the party bus with the rest of the wedding party. . . . She also danced the entire night away, including an adorable moment when she and my husband's grandmother, Bellsie, danced together," said the bride [3]. "It was amazing."

So if you're hesitating to ask somebody special to join your bridal party, don't let convention stop you — sometimes, the very best choice has been there for your entire life (and then some)!
