London, April 11
Teen sensation and "Hannah Montana" star Miley Cyrus is desperate to improve her vocabulary because her nine-year old sister keeps using words she doesn't understand.
"Noah is so annoying because she is so smart. There are times when she says some words and I have to get out my dictionary to understand it," Cyrus was quoted as saying by femalefirst.co.uk.
Cyrus also admitted that she picks on little Noah with her elder sister Brandi because the youngster talks like a grown-up.
"We kind of team up on my little sister when me and her (Brandi) are together. My mum gets really mad when we pick on her because my sister is 22 and I am 16 while Noah is just nine," she said.
