Miley Cyrus felt "anxious and insecure" working with Liam Hemsworth.

The 'Hannah Montana' star is rumoured to be dating her 'The Last Song' co-star - who she describes as her "best friend" - and although she won't confirm the romance speculation, she says she is amazed by how much they understand one another.

She said: "I've never gotten along with someone so well. I was a little anxious about making this movie; I wanted everything to be perfect. To go on set and feel insecure was a totally new element for me. But he felt the same way. He admitted his insecurities, and it was really nice to have someone who understands me for once."

The 16-year-old singer-and-actress also admitted one of the reasons why she deleted her Twitter account was to protect her relationship with the Australian actor.

She explained to Seventeen magazine: "It sucks when your personal life becomes public. So I'm finding ways to make my personal and private life more of my life - which is one of the reasons why I deleted my Twitter. We've decided that any type of relationship that we have, we will always just keep it very D.L (down low). First and foremost, we are best friends, so that's what I tell people all the time."
