Hats off to alexandra burke for two top la looks

Alexandra Burke protects her hair with a fashionable straw hat and gold headscarf while filming the video for new single Start Without You, in Los Angeles, California.

X Factor winner Alexandra makes sun protection stylish with a straw trilby accessorised with silk flowers and a thick black ribbon.

OK, so this hair might not be all Alexandra's own, but it's still a good idea to keep extensions covered up in the sun to prevent against dryness and UV damage.

Later in the shoot, Alexandra switched to a stylish gold head scarf, lending a bohemian edge to her look.

Wearing large gold hoop earrings, a crop top and micro mini shorts, Alexandra almost resembles Jennifer Lopez in this outfit, which includes a block party scene full of street dancers.

She might be filming in LA, but the video still reflects Alexandra's British roots. As the party fills out into the streets, the X Factor winner zooms away in an ice cream van, draped in a Union Jack.
