Keira Knightley not scared of ageing

Actress Keira Knightley says she isn't scared of getting older as her "early twenties were not much fun".

In an interview with Glamour magazine, the 29-year-old shared her views about ageing and said she was looking forward to her next big birthday," reports dailymail.co.uk.

The "Pirates of the Caribbean" star will turn 30 March 26.

"I'm not actually worried about turning 30. Because, honestly, my early twenties were not much fun. Then after 25, things just got better and better," she said.

"Maybe you stop caring as much about where you should be going and what other people think - which is all the s**t that makes you very unhappy early on," she added.

The actress, who got married to Klaxons rocker James Righton May 2013, also admitted that being married doesn't make her feel grown-up.

"Actually, I feel less grown-up as I go along. I reached my peak of grown-up behaviour at 20 and 21, and it's been downhill since then," she said.

"I was terribly sensible as a teenager but I've got far less so as I've grown up, which has been a huge relief for everyone - including my parents," she added.
