Jessica Alba says she keeps her hair dark because she hates having to get her roots died.

The ‘Machete’ beauty – who is known for her exotic looks – has experimented with lighter locks, but feels happier with brown tresses because the upkeep is easier

She said: ‘I’m enjoying being brunette again as I hate getting my roots done. It was so annoying because that’s not who I am. I’m the girl who wears a pony tail and baseball cap every day.’

Despite opting for simple hairstyles, the 29-year-old actress – who has two-year-old daughter Honor – believes her style is normally ‘funky’ but ‘modest’.

She explained: ‘Classic, elegant and a little funky. Yeah, I’m kind of modest in my fashion choices: I’m not somebody who puts on push-up bras and mini-skirts. I’ve played those girls in movies, but I’ve never been that girl.’

‘I’ve always had curves, especially since having Honor. I used to feel embarrassed by them, but now I feel just like a woman.’

Jessica also revealed how she has a penchant for designer splurges, and loves luxury clothes.

She told the Metro newspaper: ‘There’s not much I don’t like by Prada especially their shoes and dresses. I like Marc Jacobs bags. For casual wear, I like Juicy Couture, Diesel and Triple 5 Soul. One of my favourite dresses was one by Versace which I wore to the MTV Movie Awards.’

The 29-year-old actress admits her Catholic upbringing made her want to “break away” from her mother Catherine and father Mark.

She explained: “It’s always been weird because I grew up in a very traditional, Catholic household. My parents were very strict but I broke away from that at an early age. I was a feminist when I was five. These days, I am much more liberal-minded bit I still respect their beliefs.”

As Jessica has grown older she has learnt to accept her parents’ views, but still considers herself an independent woman.

In her latest film ‘Machete’ Jessica gets to stab a love rival in the eye with her stiletto heels, something she thoroughly enjoyed.

She said: “Walking in 3-inch heels wasn’t as much fun as putting one in someone’s eye. It was 104 degrees (Fahrenheit) where we were shooting in Texas and they were not comfortable.”

Jessica – who has a two-year-old daughter Honor with husband Cash Warren – is regularly referred to as one of the world’s most beautiful women, but she doesn’t think of herself as “sexy”.

She added in an interview with the Metro newspaper: “I don’t really pay attention to that sexy image. It just goes with the character in the movie. At the end of the day, it’s all a part of selling a product.” – Bang Showbiz
