Robert Pattinson and Nikki Reed were spotted walking home with their arms wrapped around each other.  The new couple were reportedly on a double date with Kristen Stewart and her boyfriend, Michael Angarano, in Vancouver, where they are filming New Moon.  A source stated,

Rob and Nikki spent much of the time talking to each other, heads bent close together.  Kristen and Michael hopped a cab, and Nikki and Rob walked further up the block… arms wrapped around each other on their way home.  She stayed with him overnight, was suppose to be back in L.A. on Monday… But never showed.

What do you think?  Celeb couple or friends with benefits?
