Strictly Come Dancing - Why do Chris & Orla have 'Team Cola'

[Snowstorm]

on the back of their 'yeah baby' t'shirts? The 'Yeah baby' I get, obviously. But the 'Team Cola' ... I'd understand if it were a charity thing but I thought the BBC didn't allow product promotion?

Does anyone know as I can't work it out for myself?!!

TIA

It is pronounced team colla

c for chris and ola for ola

Good job it's not Natalie & Vince

Team NAVI?

Thank you ... I'm sure I should have worked it out but just went straight for the cola drink connection!
