Paris Hilton presented her own line of perfume at an exclusive shop in Brazil with a launch party dedicated to her favourite colour - pink.

Hilton, 24, arrived in Sao Paulo to launch her namesake perfume which includes traces of pheromones which supposedly help fuel physical attraction.

"I love the colour pink and I adore parties. It seems like all girls like the colour pink," said Hilton, who chose to wear a light blue frock despite the day's pink theme. She has already launched her own jewellery line.
