The series will also involve lifestyle vlogger George Benson, and will appear on the YouTube channels of both influencers, and Diet Coke’s Facebook page. It forms part of the brand’s 2017 campaign, "Get the gang back together".
It is created by MediaCom Beyond Advertising, with MediaCom handling the media.
Natalie Whitehead-Farr, senior brand manager for Coca-Cola Great Britain, said: "The Diet Coke Break series gives us the opportunity to directly speak to our consumers during their Diet Coke break, with helpful and fun tips and tricks on beauty, fashion and travel.
"Patricia and George are both great partners to work with and their love of fashion and travel is shared by our fans."
