After Riley showed off her "whip" and "nae nae" moves on her third birthday, Leah took to Instagram -- via her dad, Cincinnati Bengals defensive tackle Devon Still -- to issue the challenge.
"I showed Leah the video of Riley doing the whip and all she kept sayin was daddy she can't do it better than me," Still captioned the video. "So I said if that's how you feel then challenge her to a dance off."
While her dad battled linemen and opposing offenses this year, Leah had a bigger fight of her own, against stage 4 neuroblastoma, a form of childhood cancer. She recently received the Jimmy V Award for Perseverance at the 2015 ESPY Awards.
"In the five years I’ve been with you, you’ve taught me more about life than I could ever do and I love you," Still said, fighting back tears, as he accepted the award on his daughter’s behalf.
Leah is still receiving treatments to fight her cancer, and while she might not have been up for the ESPYs, it seems she is ready to throw down on the dance floor!
"Riley, I saw your video," Leah challenges Steph and Ayesha Curry’s daughter, who showed off her awesome dance skills on her 3rd birthday. "You think you can whip better than me? I challenge you to do the whip."
Leah then shows off her moves, leaving a high bar for Riley to meet!
Hopefully, we’ll get to see these two throw down in an adorable dance battle, or maybe in their own buddy comedy? The possibilities are endless for these cuties!
