Leah Still Reveals Flower Girl Dress for Her Dad Devon's Wedding

— -- Last year, Leah Still, captured America’s hearts as she battled pediatric cancer, sharing her emotional journey through months of chemotherapy, surgery and radiation on social media.

The hashtag #LeahStrong was used as a powerful message of courage, which finally paid off in January 2016 when she stopped by “Good Morning America,” along with her NFL star dad, Devon Still, to announce she was cancer free at the age of 5.

Now the family is celebrating another happy milestone. Devon Still is getting hitched on May 13 at the New York Public Library. Devon and his fiancée, Asha Joyce, were chosen as The Knot’s 2016 Dream Wedding couple, allowing the magazine’s fans to vote on every aspect of their big day, from the bridal gown to the cake and even the rings.

"We're really excited," Asha said on "GMA" this morning. "I'm excited to see Devon and his expression when I walk down the aisle."

Little Leah, of course, is the flower girl.

“We created two different looks for her,” bridal designer Hayley Paige told “Good Morning America." “She wanted something that was very playful and girlie, but also really strong and fearless.”

Paige designed two bespoke looks for Leah, who couldn’t have been more thrilled to collaborate on the dress creations.

“When she came into my office we were playing the ‘Frozen’ soundtrack and I think when she puts that dress on, she’s going to feel like Elsa,” said Paige.

The end result for the flower girl dress she’ll wear to the reception is a sparkly, pink gown covered in 3D appliques, one of the hottest new flower girl trends of the season. The one Leah will be walking down the aisle in is being kept a secret for the wedding day.

Paige said the inspiration for Leah’s dresses “definitely came from a place of bravery and admiration.”

“She has such a profound effect on the world right now and her story is so inspiring, so I wanted to create something that really captured her bubbly charm and heroic sense of self,” Paige explained.
