Grey's Anatomy lives on, at least for now, but its spinoff, Private Practice, comes to an end tonight, January 22, at 10 p.m. ET/PT. Sigh. It's sad, but on the other hand, six seasons is a good run.

We know some Grey's fans have dropped Private Practice in recent years, and others never got very attached to it in the first place. However, since this could be the last on-screen adventure of Addison Montgomery (Kate Walsh) — unless she returns to Grey's — we have a feeling a lot of people are going to tune in to say goodbye.

Will you be watching tonight's finale, or do you only care about Grey's, not Private Practice? Vote with our reaction buttons, and sound off in the comments below!

Tune in to Private Practice on Tuesday, January 22, 2013, at 9 p.m. ET/PT on ABC.
