Will Miley's Little Sister Be Famous?

Miley Cyrus has been given a reminder of just how mean Hollywood can be to star kids - her little sister's self-esteem is hurting after she was rejected during a casting call.

Nine-year-old Noah is currently auditioning for roles in a bid to get spotted and emulate her hugely successful sibling.

But Miley fears for her sister's sanity and self-esteem as she competes with others to find favour with star searchers.

The 16-year-old Hannah Montana star tells Starpulse.com, "There's this whole season, dedicated to making kids come in, wearing hair and make-up, and ready to be cast.

"My little sister is one of those girls that is working on a pilot season and she'll say, 'I don't think the casting director thought I was pretty'. To hear a nine year old say that is really heartbreaking. That's what I think the hardest part about living in L.A. is."
