Angelina Jolie's elegant half-updo is a great go-to style to have in your arsenal. Below, celebrity stylist David Babaii shares how he achieved the look:

To begin, I used David Babaii for WildAid Hair Polish throughout her entire head. This provides control and additional shine to the hair. After drying her hair with a medium round brush and rounding the ends, I divided the hair into 4 sections: top, sides and back leaving the nape area free. It is imperative to make the extra effort in sectioning prior to styling so you have total control at all times.

Using a T3 large barrel curling iron, I then wrapped 1" sections around the inside of the iron and holding for 10 seconds. This creates a soft wave pattern. After curling the entire head in these loose wavy curls, take some additional Hair Polish and massage into your hands. Using only your fingers, loosen the waves gently with a soft combing action.

Next, again using only your fingers to comb, take the sides and top and comb back in a half up/half down style. Secure with pins.

Will you be experimenting with Angelina's latest look?

Whether it's the orange faux glow or the assault charges, there's just something about Amy Winehouse's appearance that has me hoping that she's simply getting in character for a guest spot on MTV's "Jersey Shore."

What do you think of Amy's sun-kissed complexion?

The model-turned-entrepreneur showed up at a book launch on Tuesday looking ... a little less than super.

Christy's stringy, lackluster style is uninspired, and more suitable for a trip to the gym/grocery store/doctor's office than a stroll down the red carpet — especially as she's rarely seen on one these days.

What do you think — could Christy use a hair makeover, or is her current look just fine?
