What shall I sing on Britains got Talent?

I'm 10 years old, but when I go on Britain's got talent I'll be 11. I'm going on with two of my best friends, the blonde headed twins ad the brunette girl(me!) I'll be the first person in the history of kids on britain's got talent that'll go on as a group band! I've got a pop voice, but I'm not so good at singing! We're going to pay for a Vocal teacher to get our voices to be amazing! So I've got a R&B voice with a little bit of Pop, so don't type in lalala songs like little Connie Talbot (I find those songs very creepy and the fact that kids sing that too!) lol
