VIDEO: Leah Still challenges Riley Curry to a dance-off

One of pro sports' most beloved kids is playfully calling out another.

Leah Still, the daughter of Cincinnati Bengals defensive tackle Devon Still, saw Steph Curry's daughter, Riley, do the whip and nae-nae to celebrate her third birthday last week. Leah thinks she's got better moves.

Here's what Devon posted on Instagram on Sunday night:

I showed Leah the video of Riley doing the whip and all she kept sayin was daddy she can't do it better then me... so I said if that's how you feel then challenge her to a dance off so @stephencurry30 the challenge has been sent #RileyKilledTheWhip #ButLeahPracticeThisDanceSoMuchSheBeFeelingHerself #SheLoveSeeingRileyOnTv

Here's the video:

Leah was diagnosed with cancer in 2014, but she was declared cancer-free after undergoing surgery to remove a tumor this past spring. Devon accepted the Jimmy V Perseverance Award on Leah's behalf at the ESPYs earlier this month.

As for her dance-off challenge, we eagerly await Riley Curry's response.
