Singing legend Mariah Carey has partnered up with Walkers for the crisp brand's new Christmas ad.

The All I Want For Christmas With You hitmaker has teased there will be "fun twists" in the festive collaboration which is set to launch in November.

“Everyone knows how festive I am, and it’s been fun getting into the holiday spirit this year with Walkers crisps – they’re irresistible!" the 49-year-old said.

This year marks the 25th anniversary of Carey's festive record, Merry Christmas.

To celebrate the occasion, the mother-of-two is heading off on an US tour named after her big hit, All I Want for Christmas is You.

Wayne Newton, head of marketing at Walkers, said on Carey's signing: “Our seasonal range of flavours – from Pigs in Blankets to Brussels Sprouts – has just been reintroduced to shelves, and we know the nation is already feeling festive as a result. But with Mariah on board too, our Christmas spirit has just stepped up a gear.

“It doesn’t get much bigger than working with a global superstar like Mariah and it’s been a big secret for us to keep – but we can finally announce that the rumours are true … the Queen of Christmas herself will be the star of our biggest ever Walkers Christmas advert.

"Keep your eyes peeled in the upcoming weeks for the ad.”

Footballer-turned-pundit Gary Lineker has fronted the savoury snack brand for more than two decades and earlier this year it was announced actress Emily Atack would be promoting the crisps too.

Meanwhile, this year saw chart-topper Carey extend her congratulations after her record for the longest-running No 1 single in the US broken by newcomer Lil Nas X.

She held the record alongside Boys II Men for their 1995 collaboration One Sweet Day before Lil Nas X overtook them with his song Old Town Road, featuring Billy Ray Cyrus.
