The youngest acts to enter the Official UK Charts revealed

As the final of The Voice Kids UK takes place this weekend, take a look at the youngest stars to land big hits on the Official Chart.

This weekend will see the first ever winner of The Voice Kids UK crowned, with the last twelve 7-14 year olds battling in this weekend's grand final.

With £30,000 and a family trip to Disneyland Paris up for the grabs, that’ll make one kid very, very happy! But what happens should the winner storm their way into the charts? They wouldn’t be the first youngsters to go up against the adult megastars of the pop world.

To see who the eventual winner may follow in the footsteps of, we’ve rounded up just some of the youngest child stars to score chart success.

The most recent act under 18 to score a Number 1 single was Shawn Mendes. The Canadian was just 17 when his track Stitches hit the top spot. Ironically, Justin Bieber was knocked from Number 1 in the process, and he made his chart debut aged 15 when One Time peaked at 11 in 2010.

As for the youngest acts to ever claim at UK Number 1 single, that honour would fall to Jimmy Osmond and Helen Shapiro. Helen is the youngest female; her track You Don’t Know reached the peak of the Official Singles Chart mountain in 1961 when she was 14. She would be the youngest chart topper ever for 11 years, and then Jimmy Osmond came along. Incredibly, Jimmy was just nine years old when Long Haired Lover From Liverpool climbed to Number 1 in December 1972. He's Officially the youngest credited chart topping artist.

Who is the youngest act to debut at Number 1? Fast-forward 25 and a half years to July 1998 and in comes Billie Piper. Aged just 15, Billie’s rebellious pop anthem Because We Want To went straight in at the top and plenty of hits were to follow. The youngest male to have a song reach the summit in its opening week is Gareth Gates – the Pop Idol runner-up took his cover of Unchained Melody all the way aged 17 in March 2002.

And now we look at even younger acts that didn’t manage a Number 1, but did make major history. In 2005, Joy Gruttman scored a Top 40 hit voicing the German cartoon character Schnappi with a song of the same name. While she’s not credited, she’s one of the youngest ever chart stars. She was seven when the song charted at Number 32, but she laid her vocals down aged just four!

Even younger than her was three-year-old Ian Doody, who under the alias Microbe, scored a Number 29 hit with Groovy Baby in 1969. The song came about after Ian, whose Dad was BBC Radio 1 newsreader Pat Doody often brought Ian into the studio. The toddler appeared on-air from time to time, resulting in how Groovy Baby came about.

Now would you believe that there has in fact been uncredited vocals on a Number 1 hit from someone under the age of 1? Well you would be right to believe, as Jessica Smith, believed to be around seven months old at the time holds the record for the youngest person to appear on a UK hit single.

Jessica was the baby who played The Sun in the Teletubbies. Famously, Tinky Winky, Dispy, La La and Po stormed to Number 1 in 1997 with Teletubbies Say Eh Oh!, and Jessica’s laugh can be heard at the start.
