Trees a Crowd: Anne Heche Drops Hubby... for Costar?

Stop me if this starts sounding vaguely familiar to faithful readers of the Ausiello Report: Anne Heche has split from her husband of five years, Coley Laffoon, her rep confirms for ET — and supposedly as the result of an affair she has been having with her hunky Men in Trees scene partner, James Tupper. A rep for Tupper confirms that he and his wife split in November, but would not comment on the rumored on-set romance.Well, at least this diverts some attention from Isaiah, right, ABC? Right...?UPDATE: Will this news make you less or more inclined to watch Men in Trees? Vote here in TVGuide.com's new poll.
