Noah Cyrus Miley Cyrus, move over.

There's a new child star in the making.

We're talking Noah Cyrus, Miley's nine-year-old sister.

Noah, known as "Noie" to her loved-ones, got all dressed up with her pal, Emma Reeves recently, for a red carpet event in Hollywood.

Wearing matching Juicy Couture bathing suits, the gals posed happily for the cameras.

But the stunt, filmed as part of their ongoing Noie & Em Show on YouTube, attracted criticism from some commentators, because of how young the two lasses are - and how grown-up they're behaving.

However, sickening as it is that the two clearly have a more glam life at the age of nine than we'll ever have, it just looks like a bit of dress-up fun in our eyes.

Who didn't want to get trussed up and play divas at the age of nine? And if you have a famous sis like Miley, you can actually live the Barbie-inspired dream...
