Hall's Killer Date in Paris

Dexter star Michael C. Hall might play a serial murderer on TV, but in real life he's all about love.

The actor was spotted with his girlfriend, novelist Morgan Macgregor, in Paris today.  The couple held hands and even smiled for photographers as they took a walk and ate at an outdoor cafe together.

Hall can be seen in the 7th season of Dexter, airing on Sunday nights on Showtime.
