It seems as though a new hair colour can not only change the way you look but it can also change your personal style. She appeared a little down in the mouth too, after being separated from her new boyfriend boxer Wladimir Klitschko.Just ask Hayden Panettiere, the actress recently dyed her blonde locks an auburn colour and now appears to have mustered up a dowdy look to go with it. The 23-year-old Heroes actress stepped out in Beverly Hills wearing a wooly hat that resembled a tea cosy teamed with a white cardigan, plain jeans and a pair of Ugg boots.

Hayden should have plenty to smile about with her new hunky lover. The towering Ukranian currently holds the IBF, WBO, IBO and Ring Magazine heavyweight titles and could be considered to be the perfect partner for her. He fits the mould of the typical tall, dark and handsome female fantasy and stands at an almighty 6ft 6 - in comparison to Hayden's tiny 5ft 1. The couple spent the New Year in Florida and Hayden reportedly postponed her flight back home to Los Angeles twice this month after she couldn't bear to be parted from her new love. In contrast to the skimpy bikinis she has been wearing in recent weeks, the TV star wrapped up warm in a pair of jeans, leather jacket and fringed sheepskin boots.
