Not all those who wander are lost. The old that is strong does not wither. Deep roots are not reached by the frost.’The quote is the opening line of the poem written by Tolkien in The Fellowship of the Ring.It intentionally reverses the older traditional proverb ‘All that glitters is not gold’, which warns that attractive things can be deceptive.Walking hand-in-hand on a dog walk in Chelsea last Friday, Millie grinned alongside Matthew before sharing a passionate moment while waiting to cross the road.The pair looked smitten and struggled to keep their hands off of one another.

He’s since turned his attention to endurance racing and ultra-marathons.His social media biography boasts of training blocks for the Barcelona Marathon in 2027, a London Backyard Ultra in 2027 and the gruelling Marathon des Sables Ultra set in the Moroccan Sahara in 2028.Matty attended Cardiff Metropolitan University between 2008 and 2013, where he received a Bachelor of Science in Biomedical Sciences and Nutrition, according to his LinkedIn profile.It’s possible that Millie met her new man on celebrity dating app Raya, which he signed up to over the summer. When she created her profile, sources close to Millie told the Daily Mail that the reality star was in ‘no rush’ to find a new relationship, but is open to ‘having some fun and getting back out there’.In her profile, Millie describes herself as a ‘creator, entrepreneur and author’, and in a nod to her delay in joining a dating app, her ‘chosen track’ which plays when someone views her profile is Lizzo’s About Damn Time.She added that someone with ’emotional intelligence’ would be the most attractive to her.Although Millie now seems content with her new man, her dating history has been far from smooth sailing.For starters, Millie and Hugo’s relationship played out publicly on the reality series Made In Chelsea where they met and started dating in 2011.And they were famously at the heart of one of the show’s best-known moments. In a scene filmed at a bar, a furious Millie had just discovered Hugo had cheated on her with her best friend, Rosie Fortescue. In true reality TV style, she exacted her revenge by throwing a drink in his face.Following the fallout, the couple split in 2011 after just six months of dating. Then Millie quit the show in 2013, with Hugo exiting shortly after.Millie and Hugo reconciled after a five-year gap, during which Millie married the rapper Professor Green, whose real name is Stephen Manderson.Her first divorce was finalised in 2016, with Millie later opening up about the relationship, describing it as ‘toxic’ and explaining that they were both going through personal struggles and mistakenly thought they could fix each other.Millie and Hugo were able to put their turbulent past behind them and got back together in 2016. They went on to marry and have two daughters, as well as a newly renovated dream £5million home in west London.However, in February, the Daily Mail reported that the couple had quietly split.
