ABC is yet to announce that the 13-episode sixth season of Private Practice will be the show's last, but it's sure beginning to look that way.

Just days after Tim Daly confirmed he would not be returning to the ABC drama, Deadline now reports that star Kate Walsh is also on her way out. She'll exit the series after these 13 episodes are over.

It's been known for some time that Walsh was interested in pursuing other avenues, considering she's played the character of Addison Montgomery for seven years when you account for her time on Grey's Anatomy.

But without ABC or Shonda Rhimes revealing whether the show will fold up without its lead, the question now must be asked: Should it? Should Private Practice go on without Kate Walsh?
