This week's fashion wrap is dedicated to the princesses of pop - Natasha Bedingfield and Sarah Berelli went for comfy and casual while Avril Levigne continued on her one woman mission to claim the bad taste crown.
Singer Sara Bareilles wore jeans, basketball boots and a scarf for her appearance on the television show MuchOnDemand in Toronto.
Singer-songwriter Natasha Bedingfield went for a low-key approach, wearing a striped top, cropped jacket, a cap and black jeans tucked into slouchy boots at a promotion for her latest release Pocketful of Sunshine.
Alicia Keys rugged up for her performance of NBC's Today Show in New York.
Ashlee Simpson chose to go for a little more glamour for the Conde Nast Traveler 8th Annual Hot List party in New York, she accessorised her little black dress with a Chanel pearl necklace.
And Avril Levigne, what can we say? Trying. Too. Hard.
