Katy and John Have a Dinner Date Following Their Family Christmas

Katy Perry and John Mayer had a holiday dinner date at LA's Matsuhisa last night. John put a protective arm around Katy as they headed back to their car, then he hopped in the driver's seat to head home. They're all about together time after reportedly spending Christmas with her parents, Keith and Mary. Katy's family welcomed John to their place in Santa Barbara, and Katy was in for a treat on the special day — she shared a photo of John Mayer dressed as Santa. Katy and John are wrapping up 2012 side by side. We'll see what 2013 brings for the duo, but are they your favorite new couple of the year?
