After hitting the clubs of Miami together, on/off couple Paris Hilton and Stavros Niarchos seem to have rekindled the flame. According to perezhilton.com, the pair is going to London together, for a romantic, rock 'n' roll trip. "They're going for a romantic getaway and to go to the Led Zeppelin concert," a source tells Perez. "They spent all week in Miami, shared a room together, and find it funny that nightclubs are starting rumors that there's been any drama." Perez says the twosome may stop over in Paris on the way back.
