Get ready for an overload of adorableness.

Riley Curry, the charismatic daughter of NBA MVP Stephen Curry, celebrated her third birthday last week with plenty of dancing, including her rendition of the whip and nae nae.

Well, Leah Still, the 5-year-old daughter of Cincinnati Bengals defensive tackle Devon Still, saw Riley's moves and is challenging her to a whip/nae nae dance battle. 

To see Leah in good spirits is a great sight, considering she just finished her final radiation treatment for the Stage 4 pediatric cancer last week. Leah has battled the disease for over a year, and she was recently given the Jimmy V Perseverance Award at the ESPYs.

Now, let's see if Riley accepts Leah's challenge!
