A year ago, Leah Still was weak and bedridden after a setback in her battle against cancer. On Friday night, she was healthy and happy, getting her boogie on at dad Devon Still's wedding.

Devon and his fiancee Asha had put their wedding on hold while Leah was fighting for her life, but once she turned the corner they took the plunge, and The Knot offered to throw them their dream wedding.

That turned out to be a ceremony of about 200 at the New York City Public Library. Leah was the flower girl.
