Norfolk's YouTube power couple Tanya Burr and Jim Chapman will be kicking off the festive season in Norwich this evening.
The couple will illuminate thousands of bulbs around the city centre at the Christmas lights switch-on, with festivities getting underway from 6pm tonight.
The event will include live music and a colourful Christmas parade and will end with a fireworks display.
The couple have shot to stardom with their videos and product lines on YouTube in the last few years.
Miss Burr, who grew up in Norwich, attracts millions of views each month with her make-up and style tutorials, while former UEA student Mr Chapman, from Attleborough, has built up followers with his videos on life and fashion.
At the switch-on, a parade led by Santa Claus' sleigh will wind its way from Norwich Cathedral through Tombland, Queen Street, London Street and Castle Street, up through Dave Place, Gentleman's Walk and Hay Hill to The Forum.
Local soprano singer Emma Nuule, musicians from The Garage, Creature Feature pantomime There's Nothing Like a Dame, acrobatics and a choir will keep crowds entertained.
Just before 7pm, the Revd Robert Avery, the new vicar of St Peter Mancroft Church, will lead a prayer before the Christmas lights are switched on by the YouTube newlyweds, who tied the knot in Somerset last month.
Disabled seating will be by the war memorial.
