Millie Mackintosh Makes Relationship Instagram Official With New Boyfriend Matthew Tanner

Millie Mackintosh has publicly confirmed her new relationship with Matthew Tanner, sharing a series of photos on Instagram eight months after her separation from husband Hugo Taylor. The former "Made in Chelsea" star, 37, posted a selfie with Tanner, 38, who captioned the image "This girl" alongside affectionate emojis and noted "Perfect Sunday feels."

Mackintosh and Tanner made their first joint public appearance on Thursday at the Boodles Old Bond Street flagship opening, where they were observed browsing diamonds. The week prior, they were seen holding hands during an outing in Chelsea.

Tanner works as a Global Solutions Director and Programme Director at Robert Walters Consultancy. His Instagram profile, which has over 4,600 followers, reveals shared interests with Mackintosh, particularly in fitness. Like Mackintosh, Tanner is a fitness enthusiast and has previously played amateur rugby before an injury led him to focus on endurance racing and ultra-marathons. His social media indicates training for events such as the Barcelona Marathon and the Marathon des Sables Ultra.

Tanner attended Cardiff Metropolitan University, where he earned a Bachelor of Science in Biomedical Sciences and Nutrition. Mackintosh reportedly joined the celebrity dating app Raya over the summer. Sources close to her indicated at the time that she was not rushing into a new relationship but was open to "having some fun and getting back out there."

On her Raya profile, Mackintosh describes herself as a "creator, entrepreneur and author." Her chosen track for her profile is Lizzo's "About Damn Time," and she stated that a partner with "emotional intelligence" would be most attractive to her.

Mackintosh and Taylor officially filed for divorce in February after seven years of marriage. The couple shares two daughters, Sienna, six, and Aurelia, four, who now divide their time between their parents' separate homes. Their relationship was previously documented on the reality series "Made in Chelsea," where they first met in 2011. The pair experienced a public breakup that year after Mackintosh discovered Taylor had cheated on her with her friend. They later reconciled in 2016 after a five-year gap during which Mackintosh was married to rapper Professor Green. Following their reunion, they married and had their two daughters. After their recent split, Taylor posted a quote from Tolkien's "The Fellowship of the Ring" on his Instagram, which reversed the proverb "All that glitters is not gold."
