Paris Hilton and boyfriend Doug Reinhardt are mixing business with pleasure on their whirlwind trip through Europe.
First stop: Budapest where Paris celebrated the launch of her clothing line at The Coin Store. Hungary apparently loves Paris because the store's first order sold out immediately and they've already re-ordered.
Friday night Paris and Doug went on to the Venice Film Festival premiere of Bad Lieutenant: Port of Call New Orleans starring Nicolas Cage and Eva Mendez.
The couple was on hand to lend support to Doug's business partner, Alan Polsky, a producer on the movie. The hotel heiress rocked the red carpet in a couture gown by British designer, Jenny Peckham.
"We are having such a lovely time," Paris told RadarOnline.com. "Venice is such a beautiful city and the shopping is amazing. Loves it!"
On Saturday, Doug took his favorite girl shopping in Venice. "Doug whipped out his black Amex card and took Paris on a major shopping spree," an eyewitness told RadarOnline.com. "They went to Cartier where he bought her the entire diamond Panther collection of rings, necklaces, and bracelets.
