JUSTIN Bieber is not the only child muso getting hits on YouTube. Far from it.

While a performance by the Canadian pop sensation at Sydney's Circular Quay was cancelled following reports of fans fainting last month, by the end of this month girls could be passing out over a new teen sensation. It's what we're penning 'the Bieber effect'.

Here are our top three YouTube clips of the week, featuring up-and-coming talent from Australia and abroad ...

  1. American YouTube sensation Greyson Chance appeared on TV show Ellen this week after his rendition of Lady Gaga's Paparazzi went viral on the popular video sharing site. The 12-year-old's clip has almost 10 million hits to date.
     
  2. Teenager Bobbi Andonov continued to turn heads on Australia's Got Talent in the semi finals this week. The 15-year-old, already being labeled Australia's own Justin Bieber, shocked judges and viewers when he sang Hallelujah at his first audition.
     
  3. Fellow Australia's Got Talent semi final contestant Shuan Hern Lee has a few years before he becomes a teen sensation, but his talent surpasses most adults'. The seven-year-old piano prodigy has been performing since he was two years old and wants to tour the world playing music.
