Nicky Hilton NHILTON120607_01.jpg They say into every life, a little rain must fall - even Nicky Hilton's!

Yes, while Paris was partying promoting her scent in sunny Miami last night, her little sister was back home in Hollywood dodging the raindrops on her way into Goa. Good thing her boyfriend David Katzenberg had an umbrella big enough for two!

Luckily, Nicky and David weren't the only celebs to brave the torrential downpour (well, by LA standards, anyway) - we also caught Amy Smart, Lauren Conrad, Sean Stewart, and a Lachey-less Vanessa Minnillo stopping by!
