Serious PDA alert! Christina Aguilera and Matthew Rutler were spotted making out in the back seat of their car in LA on Saturday. The duo had dinner with friends at Giorgio Baldi and apparently couldn't contain their passion as they headed home for the night. Christina and Matthew have been lying low following their arrests earlier this month, and it looks like the couple is moving on since the run in with the law. Christina's focusing on the music scene and also prepping for her new job as a judge on The Voice.
