Does anyone know if anyone is holding auditions for singing?

I am a 13 year old girl with a good voice. My ambition is to sing with beyonce or mariah carey which probally will not happen without a record deal. I went to an audition at britains got talent and they told me they would call me back but they never did! Can anyone if they are aware of auditions please comment below ! I will be sooo sooo gratful! Thank you xx
