Fans of Kylie Minogue’s bum will be disappointed to hear that it’s not as pert as it used to be.

The I Can’t Get You Out of My Head singer admitted that now that she is in her forties her famous backside is not quite what is used to be.

The Aussie star said: “I don’t think I can live up to expectations. I see myself in the mirror every morning and it’s not the same as what everyone else sees. It’s a less polished version”

According to The Sun, the tiny star also revealed that she is a fan of self help books and credits them for helping make life changes decisions.

The 45-year-old admits that she loves Malcolm Gladwell’s book Blink: The Power of Thinking Without Thinking and claims that it helped her decision to join The Voice UK and sign with Jay-Z’s record label.

Kylie said: “I met with [Roc’s co-founder] Jay Brown and I happened to be reading a book called Blink: The Power Of Thinking Without Thinking at the time, which helped me decide in the first 60 seconds that I met him, ‘You’re the one, let’s do it’.”
