Singer and Strictly star Pixie Lott is to perform in the window of a shop at Westfield Stratford shopping centre next month.
She is the first celebrity to be named in Christmas Window Live, a real time Sky Arts event which will take place in the first two weeks of December at the east London retail hub.
Details of her 15-minute appearance are being kept a closely guarded secret but Sky has revealed that the series will feature a performance every evening in December from the 1st to the 13th (excluding the 7th) in the window of a working store.
The full line-up is yet to be confirmed but violinist Tasmin Little will also be participating, the broadcaster has revealed.
Sky adds that the performances will range from dance displays to readings from well-known actors to rock music to a capella singing.
If you can’t make it to east London, each one will be broadcast live on Sky Arts, finishing up with a 60-minute compilation episode offering the best bits from the whole event.
Alongside The Christmas Window Live, Sky Arts will air a one-off Playhouse Presents… Christmas special called Marked starring Stephen Fry and Kiefer Sutherland, following their recent appearance together in 24: Live Another Day.
Marked sees Sutherland’s debt-ridden character James agree to perform an assassination for his neighbour in order to make some money before meeting Fry’s character who is “the last person he expects to see” according to the broadcaster.
December will also see the premiere of The Great Culture Quiz on Sky Arts, hosted by Anita Rani. The quiz pits two arts organisations against each other to test their knowledge on the arts, and their own institutions, in a bid to become the Great Culture Quiz champion.
Another seasonal treat sees comedian Adam Buxton exploring Christmas in Adam Buxton Loves… Christmas. Filmed from his own garden shed, Buxton will examine what Christmas means to him personally as well as to the nation.
Sky Arts director Philip Edgar-Jones said of the new line-up: “We love the magic of Christmas and we wanted to make sure the channel reflected the joy of the season with a mix of the familiar, the fun and the unusual. So we are delighted our customers will be enjoying traditional carols – whether they’re jazzed up by the National Youth Jazz Orchestra or beautifully sung by Katherine Jenkins at the Classic FM Carol Service. Then there’s the quirkier offering, from the brilliantly funny Adam Buxton reflecting on the perfect Christmas and our shop window takeover. Beat that, Santa.”
