Jennifer Aniston  and Owen Wilson  had lots of smiles for the cameras this morning at the Rome photo call for Io & Marley . Jen traded in her floral print dress  for basic black and looked comfortable as usual on her costars arm. This time the two got to pose against a pretty outdoor backdrop. Owen enjoyed Paris with Kate Hudson  last weekend so maybe there will be a choice for John Mayer  to come join Jen for a little European vacation while she's overseas.
