Castle wrapped production on season seven, which explains how Katic was able to sneak away to get hitched! But as of now, the long-running show hasn't been renewed for an eighth season. The Canadian-born actress has alluded to her potential departure from the show, telling TV Line that should her character run out of a storyline, she would leave the show.

"If the character is complete, if there is nowhere else to go creatively, then I think it's better to stop when you're on top," she said. "So for me it's about art over finance, and as long as we're creating something that is compelling and that has somewhere to go, then we're good to go."

Naturally, Castle fans freaked out. They also panicked when Katic hinted on Twitter about a potential series finale of the show when season seven ends. She responded to a fan's question, writing, "Proud of all we've accomplished. Grateful 4 being part of the ride."
