The challenge was inspired by Ellis

The challenge was inspired by Ellis-Bextor's Kitchen Disco sessions - a series of live-streamed concerts from her house during the 2020 lockdown.

She was often joined by her children for the events, and they're expected to help her sashay across the finish line on Wednesday morning.

"I'm trying to raise dancers, I get them to use their hips," said the star, whose five sons age between two and 17 years old.
