Paris Hilton was left with a swollen and grazed chin after being swarmed by paparazzi in Prague last weekend. The hotel heiress is touring with boyfriend Benji Madden and his band Good Charlotte in Europe, and her presence has attracted paparazzi in every country. She was leaving a music store with Madden on Sunday in the Czech Republic when hysteria broke out among the photographers waiting outside. Hilton, who has size 11 feet, tripped while rushing to get to a waiting car. Madden stepped over her, then turned and helped her get up. Hilton was seen with a large bruise on her chin the following day at the Good Charlotte concert.
