Paris Hilton and her boyfriend River Viiperi attended the 5th Annual Gala Benefiting the European School of Economics Foundation "Family Business Dynasties" in New York City last night, and the two looked amazing when they posed for a few snapshots outside.
And yes, the lovebirds coordinated their outfits! River tweeted a pic of himself on the way to the event and wrote, "Picked the blue one, matches better with my baby Paris Hilton's dress #Ready."
River and Paris weren't the only ones who dressed to impress! P's little sister Nicky took our breath away in this stunning red gown:
