Erin Krakow has been dropping hints all over the place about the upcoming season of When Calls The Heart.

The series, now in its 10th season, is set to premiere on Sunday, July 30 on Hallmark Channel, and fans can’t wait.

In a recent interview with ET, Erin teased that there are a lot of guest stars coming in this season.

“We are bringing in lots of exciting guest stars,” she teased. “We’ve don’t know if they are good guys or bad guys.”

That got Just Jared thinking of just who the “exciting” guest stars were and if they were her co-stars from other Hallmark Channel projects.

While Niall Matter, who Erin starred with in the Father Christmas series, has already popped up on the show – is it Tyler Hynes, Ryan Paevey, Luke Macfarlane, Kimberley Sustad or even Brendan Penny‘s turn?
