Smooth operator! There's a definite trend in celebrity tresses this week with Camilla Belle, Keira Knightley and Holly Valance all pulling their strands back into a sleek up 'do with a deep side part. Camille was at the Ralph Lauren soirée hosted by Oprah Winfrey on Monday evening and finished her look with blue shadow worn as liner and a raspberry lip. On the same night across the pond in London at the premiere of A Dangerous Method, Keira sported an equally sleek style, teaming hers with a classic smoky eye and nude lip combo, whilst Holly went with a pink lip, winged liner and the same style at the Candy and Candy book launch yesterday. To replicate the look, you'll need three things: a styling cream, a tail-end comb and a serum.
