Britain’s Got Talent judges have been bowled over by a 10-year-old star-in-the-making after she captivated them with a Vera Lynn classic.

Chloe Hickinbottom turned back the clock to perform White Cliffs Of Dover by the Forces sweetheart – and won a place in the second round of the series.

She was among the star performers as producers gave a sneak preview of the fourth series, which also features naked balloon dancers, a wannabe who burps songs and an ex-footballer turned dancer.

Wearing a black-and-white checked dress with sequinned leggings, the youngster impressed Amanda Holden, Piers Morgan and stand-in judge Louis Walsh at the Birmingham auditions. Chief judge Simon Cowell was off sick with flu.

“You have an old-fashioned big voice,” gushed Amanda.

Piers added: “You have an extraordinary voice, I have never heard anything like that. You’re a star.”

Meanwhile teenage drummer Kieron Gaffney, 13, who narrowly missed out on the semi-finals in 2009, was given a second chance by the judging trio at the London auditions. “Last year you were good, but this year you are fantastic,” exclaimed Simon.

The fourth series of the ITV1 show, which screens on Saturday at 8pm, heads to cities around the country including Newcastle, Manchester, London and Birmingham to search for a winning act to perform at the Royal Variety Performance and scoop £100,000.
