Heading to lunch together, Blake Lively and Ben Affleck pal around on set right after shooting a sex scene together on their upcoming film, “The Town,” in Boston, Massachusetts on September 01, 2009.

Seems like an odd couple to me.  What do you think?

The crime thriller is based on Chuck Hogan’s “Prince of Thieves” and – in addition to playing the lead – Affleck is also directing.

Lively, aka “Gossip Girl’s” Serena van der Woodsen, plays Affleck’s ex-galpal and Renner plays her brother and Affleck’s best friend. Jon Hamm has the role of a hard-charging FBI agent who is hot on the trail of bank-robber Ben.
