Victoria Beckham Turns Rock Chick At LAX Airport

Victoria Beckham usually channels a very Posh sense of style. So we were quite surprised to see her rocking out at LAX airport on Wednesday.

Instead of her usual pencil dress look, the designer was spotted releasing her inner rock chick in a Grateful Dead tribute T-shirt featuring a large skull on the front.

The Grateful Dead were an American rock band formed in 1965 in Palo Alto, California, known for their eclectic mix of folk, blues, rock and psychedelia.

But Vic, of course, didn't eschew all sense of glam, and finished the look with a vertiginous pair of Christian Louboutin ankle boots.

Her Citizens of Humanity jeans could also be dressed up or down, and a pair of designer shades added extra star power.

Meanwhile, Victoria recently joined a throng of celebrities taking part in the ALS Ice Bucket Challenge.

Luckily for her, she had her four boys (David, Romeo, Cruz, and Brooklyn) on hand to do the honours.

The 40-year-old was nominated by Eva Longoria to support the Amyotrophic lateral sclerosis (ALS) Association.

She was seen in her garden dressed in her gym kit and nominated celebrity pals Katie Holmes and Tom Ford to carry out the next challenge.

The Beckhams have been joined by a host of stars taking part in the Ice Bucket Challenge, including Cheryl Cole, Anna Wintour, Sarah Jessica Parker and Jennifer Lopez.
