"We are family" - that was the message the Hilton sisters were giving as they boogied the night away at dos in two different cities thousand of miles apart this week.
The owner of a little black book as long as her elegantly toned arms, Paris surely has her pick of party companions. But it's nearly always little sister Nicky's number the vivacious heiress dials when she's in the mood for some fun.
On Wednesday the glamorous siblings turned up to a blinging bash hosted by hip-hop producer Pharrell Williams in New York.
Even in a roomful of rappers weighed down by their weight in gold the girls, both currently single, made quite an impression. Paris chose to be a scarlet woman for the evening, wearing a red minidress with ankle boots.
A dinkily dressed Nicky, meanwhile, was in silky shorts teamed with a black cami top.
With air miles not a problem, the wealthy sisters spent the previous evening at Caesars Palace in Las Vegas. This time Nicky had been called in to lend moral support at a launch party for Paris' debut album.

Having split with Greek shipping heir Stavros Niarchos, Paris is free to date again. But for now the hotel heiress, who says she's enjoying being single, prefers to step out with her little sister Nicky to parties like this one in New York
