and Selena Gomez
didn't let the grim subject matter of Contagion
scare them off from sharing germs during their movie date. The happy couple
engaged in a little PDA when checking out the thriller at Atlanta's Phipps Plaza, holding hands while waiting in line to buy their tickets. Gomez also affectionately rubbed her boyfriend's back while they waited for the flick.
