Petra & James Pictures

More pictures of British singer James Blunt and his Czech supermodel girlfriend Petra Nemcova in Prague have surfaced.  Taken late last week, the couple enjoyed a stroll through the streets of the Czech capital.  James is currently performing the final dates of his European tour.   Petra, 26, and James, 29, walked hand in hand and looked happy as ever. "The music gives you more energy for your work," Petra said of James‘ work. "And thanks to it, you also feel more sexy."  More pictures in the gallery!
