Miley Cyrus comes across as a spoilt brat

LAST year, while reviewing her first film, I wrote that I thought Miley Cyrus was a better role model than Britney Spears.

I take that back. Now Britney has cleaned up her act and trying to be a good mum, she's proving to be a much more pleasant person than Miss Cyrus, judging from the 16-year-old's appearance on Friday Night With Jonathan Ross.

At first, gum-chewing Miley came across as merely over-confident as she blew her own trumpet, telling everyone how she had her fourth number one record. That soon turned into a rude spoilt brat, as she called Helen Mirren "her".

When Jonathan replied "Come on, she's in the room, she's not the cat's mother!", Miley was having none of it.

"This is all about me, this is my press time, let's talk about MY movie!" she yelled.

Then she just started shouting and brow-beating Jonathan into plugging her movie.

"You're like a sort of charming assassin, aren't you? You are the scariest person!" he said. Umm, less of the charming, I think.

Later, when the cameras cut to the other guests in the green room politely listening to Helen MIrren, she was ignoring everyone else while she texted on her phone. After all, her moment in the spotlight was over, so why bother with anyone else?

I don't think she used to be quite this bad, but global fame has changed her and created a monster.

Miley, you may be a talented girl, but have a little respect for your elders and betters.
