It was one of the crowning moments of Noel Gallagher‘s long career as he was named Songwriter Of The Year at the Brit Awards on his home turf in Manchester. 

But sitting next to him and cheering him on as he enjoyed the plaudits at the Co-Op Live arena last weekend was not long-term girlfriend Sally Mash but another woman.

The 58-year-old had quietly parted ways with Ms Mash after two years several months ago.

The Mail on Sunday can reveal he has since ‘grown close’ to socialite Tori Cook.

Friends of the pair have told the MoS: ‘Tori and Noel are getting on really well and are enjoying each other’s company.’

Ms Cook, 44, is understood to have split from her husband of three years, Hugo Heathcote, with whom she has two daughters, and has been friends with the Wonderwall songwriter for almost a decade. 

The publicist, who had Sienna Miller as a ‘mate of honour’ at her wedding, partied with Gallagher at a Brits after-party in Soho House, enjoying cocktails with his daughter Anais, 26, with whom friends say she ‘has formed a bond’.

Ms Cook joined Oasis on tour last year and was pictured cheering Noel on from the crowd in South America, standing next to Ms Mash.

She also appears to be friends with his ex-wives, Sara Macdonald and Meg Mathews. 

One holiday snap from 2017 reveals Ms Cook with Mr Heathcote, posing alongside the rocker, Ms McDonald and their children.

Mr Gallagher split from Ms Macdonald six years later and, within a few months, had struck up a romance with Ms Mash, a high-society events manager, who was often pictured at parties with Ms Cook. 

Gallagher and Ms Cook have been contacted for comment.
