It's a beautiful day for Devon Still and his adorable daughter, Leah.

After the Houston Texans defensive tackle hung tough by Leah's side as she bravely fought and defeated pediatric cancer this past December, Devon's pride and joy will be by his side as he marries his girlfriend, Asha Joyce, in a New York City wedding on Friday.

By the looks of Devon's Instagram, little Leah couldn't be any more excited to serve as the ceremony's flower girl, shouting out her role to anybody who would listen in the Big Apple.

Yes, this courageous, adorable 5-year-old just won our hearts all over again. Just last month, Devon gushed about Asha being there for him and his daughter during her cancer battle, which started when she was diagnosed with neuroblastoma in 2014. The couple was actually supposed to get married earlier, but held off their plans for Leah's brave and successful fight.

"All my focus was on my daughter and everything I needed to do to help her beat this disease and it took a lot away from my relationship," Devon told Daily Mail Online last month. "But no matter how bad it got, Asha stood there by our side, and she fought her way through, which I know was hard for somebody to be in a relationship and feel like they're in it by themselves."

He added: "Just to be able to make it through something like that as a couple, I don't really think there's anything out there that can break us apart because we've been through the hardest parts you can go through."

Still standing. 

Clap for this couple! Congrats!
