Robbie Williams has been revealed as a brand ambassador for WW, formerly known as Weight Watchers, alongside Oprah Winfrey and Kate Hudson.
The X Factor judge will use his personal weight journey to encourage others to be healthier in 2019.
He is one of several ambassadors in the Every Body Matters campaign.Weight Watchers rebranded as WW, dropping the 'Weight' reference, in September and now aims to focus on wellness and health.
Williams will be sharing his "wellness journey" on social media, using the hashtag #MyWhy.
He said: "WW is the first programme that truly feels like it fits with my life.
"After my back injury last year, I definitely let my healthy habits slip and I felt as though I let myself and my family down.
"I can't keep trying the same things and hoping for a different outcome.
