OHMYGOSSIP — Lauren Conrad insists Sienna Miller is her style icon and loves her effortless look. The 28-year-old star covets the British actress’ “beautiful” blonde waves and insists it looks effortless.

She told people.com: “I’ve always loved her hair. It’s so beautiful and easy. It looks like she rolled out of bed — and she probably did!”

Lauren insists her hair won’t grow as long as she wants it to go, even though she’s tried a number of different techniques to try to get it to lengthen.

She added: “My biggest hair mistake it was chopping it off! It’s so funny.

“My hair won’t grow – my hair has not gone past this length since I cut it seven years ago to my shoulders. I’ve tried vitamins, I’ve tried everything. It just won’t!”

The screen beauty – who was catapulted to the spotlight on reality show ‘The Hills’ – prefers a natural look and enjoys getting ready for her day.

She added: “Day to day I don’t wear a lot of makeup and my hair is kind of, you know, just waves, I definitely love getting dressed up … but I think lower maintenance is easier. [The key is to] have fun with it, really. It shouldn’t be a task … I know that sounds silly, but you should enjoy getting ready for your day.”
