Anne Heche Splits with Husband

Anne Heche, the star of ABC's "Men in Trees," has split from her husband of five years, Coley Laffoon.

The 37-year-old actress and Laffoon, 33, "have decided to separate," Heche's rep says in a statement to People. "They have requested that they be allowed their privacy at this time."

Meanwhile, "Entertainment Tonight" is reporting that Heche and her "Men in Trees" co-star, James Tupper, have begun dating. Neither actor, per their representatives, is commenting on the alleged romance. The two play on-screen lovers in the ABC series, which is set in a small town in Alaska.

Tupper and his wife separated in November, "ET" says.

Heche and Laffoon married in September 2001, a year after she ended a three-year relationship with comedian Ellen DeGeneres. They have a 4-year-old son, Homer.

"Men in Trees" airs at 10 p.m. Thursdays on NBC.
