Holly Willoughby as Diet Coke ambassador

Diet Coke has named ubiquitous TV presenter Holly Willoughby as its UK brand ambassador for 2017.

The host of ITV shows including This Morning, Surprise Surprise, Play to the Whistle and Meet the Parents will lend her voice to ‘an exciting programme’ of promotional activity.

The former underwear model joins the likes of pop star Taylor Swift as a face of the world’s leading diet soda.

Willoughby was a longstanding fan of Diet Coke, she said. “The brand is well-known for celebrating friendship, fashion and fun, which are all very important to me. I’m excited to be involved.”

Simon Harrison, operational marketing director for Coca-Cola European Partners GB, claimed the Celebrity Juice panellist was “the perfect partner for us”. He added: “We’re proud to be working with Holly to bring some extra sparkle to Diet Coke activity this year.”
