Grey's Anatomy: Is Matthew Morrison Playing Jo's Husband?

The Glee alum was spotted filming a scene with star Justin Chambers on Friday -- the same day Morrison teased on Instagram that his next role is a character named Dr. Paul Stadler (all without ever saying the phrase "Grey's Anatomy," of course).

[...] while neither ABC nor Morrison have yet to officially confirm the news, TVLine reports that not only is Morrison joining Grey's as a new doctor, but he's actually playing Jo's (Camilla Luddington) estranged husband!

[...] Jo's terrifying ex has only been discussed, but never seen... until now, perhaps.

Adding to the evidence that Dr. Stadler is likely the same person as Jo's ex is the fact that just last month, Grey's was looking to cast a doctor who is "appealing, charismatic and charming," but with a "manipulative, scary dark side" -- descriptors that definitely would apply to the man Jo ran away from.
