REPORT‘Glee’ Alum Matthew Morrison Joins Cast of ‘Grey’s Anatomy’ — Is He Playing Jo’s Husband?

Matthew Morrison is trading in glee for gloom!

The 38-year-old former Glee star is reportedly joining the cast of Grey's Anatomy in a guest starring role. TVLine originally reported that the medical drama was looking to cast a character who is "appealing, charismatic, and charming,” yet "manipulative" with a "scary dark side." Fans of the show were quick to point out that the description sounds like it could be for Dr. Jo Wilson's abusive husband!

E! News recently confirmed that Matthew will, in fact, join the cast later in Season 13. The actor previously posted a video to Instagram letting fans know that his next character is named "Dr. Paul Stadler," but wouldn't reveal any other details.

If Matthew is joining the cast to portray Jo's husband, what will that mean for Camilla Luddington's character's relationship with Dr. Alex Karev (aka Justin Chambers)? One of the main questions from this season is whether Alex and Jo will be able to reconcile after his arrest for physically assaulting Dr. Andrew Deluca (Giacomo Gianniotti).

Photos recently surfaced on Twitter showing Matthew and Justin on the set of Grey's Anatomy, which further supports the theory that Matthew will play Jo's husband.

Executive producer and star Debbie Allen previously admitted that introducing Jo's husband as a character in the show is a serious possibility.

"It’s the elephant in the room, the one piece that we have not been able to fit into the puzzle of why they [Alex and Jo] have not been able to get married, what she’s been holding back and what she’s been dealing with," she said. "It gives us great story."

Looks like the drama at Grey Sloan Memorial Hospital is just beginning!
