Anne Heche's Men in Trees
costar James Tupper recently bought a new home in West Vancouver, where he's living with the actress – a situation he says "feels a little bit like heaven," he tells his local newspaper.
"We are just exploring our relationship and it has been going very well," Tupper, 42, says to the Vancouver Sun
. "Where is it going? I don't know. Ask me again in a year."
As for their current situation together, Tupper says, "Canadians are so respectful, they really leave us alone a lot. We have experienced nothing but generosity and openness."
Before going back to work on the second season of the ABC show about a big city therapist in a small Alaskan town, Tupper and Heche, 38, spent three-and-a-half months in Los Angeles with Homer, Heche's 5-year-old son from her former marriage
to Hollywood cameraman Coley Laffoon.
"He is unbelievable," Tupper says of Homer. "We had a cast baseball game on the weekend and he came off and slugged it over the short stop. He has got a preternatural swing."
It was while shooting the show that Tupper and Heche first became friends who, he says, kept very clear boundaries.
"In that friendship, we kind of discovered we saw the world in a somewhat similar way," says Tupper, who's originally from Nova Scotia. "I think we both made decisions that were based on the relationships we were in. "
Yet the friendship eventually blossomed into something more, and the couple started dating
As for his costar on and off the screen, Tupper says, "I wish people could meet her in person. She has such a sparkle and such a love for people and she works so hard. She is so dedicated to all the good things."
