She was often rumoured to be dating her Castle co-star Nathan Fillion, who her character married on the show. But the couple were never an item, according to Stanic. Her last Instagram post was not about her wedding, however, but about her show Castle, which wrapped production on season seven recently. It is not known if the cop series will get an eighth season. Katic told TV Line she would be fine with the show ending if it needed to. '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,' the beauty 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.' A big success: The actress (center) with (left) Nathan Fillion on a March 30 episode of Castle . On Twitter she has made it seem like the end is near: 'Proud of all we've accomplished. Grateful 4 being part of the ride.' The season seven finale of Castle airs May 11. Stana got her first big break in the James Bond film, 2008's Quantum Of Solace.
