Paris Hilton And River Viiperi Go On A Shopping Spree

After Paris Hilton and beau River Viiperi spent most of last week on business in Europe (she had some promotional appearances while he worked the runway for Barcelona Fashion Week), the lovebirds indulged in a little retail therapy on Monday afternoon.

While the heiress is obviously a regular at Barneys New York, it looks like she's going to have a new hot spot pretty soon! "So excited they are opening a @TopShop in LA!" she tweeted. "One of my favorite stores, always find so many cute things in there! #Shopaholic ;)."
