She has never come across as the shy type but Christina Aguilera didn't care who was looking as she packed in the PDA for a passionate make-out session with boyfriend Matthew Rutler, and RadarOnline.com has the pictures.
The pair was spotted passionately making out in the back seat of a chauffeur-driven car as they left Il Ristorante di Giorgio Baldi in Santa Monica, CA. They were in full view of other patrons waiting for their cars and several photographers.
Christina, 30, and Matthew, 25, had hired a driver for the evening. Almost comically, he's seen sneaking a peek in the rear view mirror as the pair acted like naughty teenagers.
Matthew was arrested on March 1 and charged with DUI, after he was pulled over by cops in West Hollywood.
He is currently out on $30,000 bail.
Christina, who was in the passenger seat at the time, was also arrested for public intoxication but released without charge.
The two met last year when he worked as a production assistant on her movie Burlesque. She finalized her divorce from Jordan Bratman in February.
