Kelly Osbourne thought Miley Cyrus was a “perfect Disney b***h” when she first met her.

The pair are now close friends, but Kelly admits to having preconceived ideas about the Hannah Montana star when they were first acquainted.

Kelly realised her fears about Miley were unfounded though.

“When I first met Miley, I thought ‘You’re too f**king perfect, you Disney b***h!’ But I love her – she’s got a level head on her shoulders – unlike so many silly LA girls,” she told British magazine Closer.

Miley was also involved in the interview and revealed the secret behind her svelte figure.

The 19-year-old singer-and-actress has claimed Pilates helped her achieve a slimmer physique.

“I started two months ago and I think I’ve already lost a dress size!” she exclaimed.

The stunning star showed off the results of her weight loss during the recent Hollywood awards season.

She wore a gorgeous silver Roberto Cavalli gown to the Vanity Fair Oscar party which boasted long sleeves and satin panelling, as well as a flowing chiffon skirt.
