Actress Anne Heche is expecting a baby with actor James Tupper, whom she met while shooting the now-cancelled ABC series “Men in Trees.” The couple began seeing each other in 2006, while Heche was still married to cameraman Coley Laffoon and Tupper to actress Katherine Mayfield. Heche and Laffoon became embroiled in a lengthy custody battle over their son Homer, especially his spending time in Vancouver with Heche and Tupper in Vancouver during the shooting of “Trees.” Heche previously had a well-publicized relationship with Ellen DeGeneres that lasted three years. No word yet on whether the prospective parents plan to marry in the future but Heche’s rep says they are “thrilled” to be expecting.
