Lauren Conrad has had to tone down her ''girlie'' home since her fiancé moved in.

The former 'Hills' star is a fan of overly feminine and vintage styles of decor, but admits her partner William Tell doesn't share her tastes.

She said: ''If it was up to me, my home would just be over-the-top girlie and vintage but I share my home with a gentleman now.''

And the 28-year-old beauty is trying to curb her habit of working from her bed.

Speaking to the new issue of Allure magazine, she said: ''Your bed is for sleep and sex.''

The fashion designer also revealed the key to her laid-back style.

She explained: ''Take any trend you want and relax it. That's how California does it. If it's silk button-up shirts that are in, you probably don't button them all the way, and you cuff a sleeve, you know what I mean?

''It's almost like how your outfit looks at the end of the day.''

Lauren is a big fan of hair extensions and wouldn't be without them to boost her locks.

She said: ''I can't remember the last time I didn't have extensions.

''Extensions are great. And they've come so far in the last few years.''
