Anne Heche's husband has filed for divorce after five years of marriage, citing irreconcilable differences. In documents filed Thursday, Coleman Laffoon asked the court to award him spousal support and joint custody of the couple's 4-year-old son, Homer.

The filing lists as separate property his earnings from the date of separation and "miscellaneous jewelry and other personal effects."

Heche, 37, and Laffoon, a motion picture cameraman, were married in September 2001. The couple met while working on a documentary about Ellen DeGeneres' return to standup comedy.

An after-hours message for Heche's publicist, Lisa Kasteler, was not immediately returned Friday. Kasteler announced the couple's separation nearly a week ago, but did not elaborate on the reason for the split.

Heche had a high-profile relationship with DeGeneres for more than three years. They announced their separation in August 2000.

Heche currently plays a relationship guru who relocates to Alaska in the ABC television drama "Men in Trees." Her film credits include "Wag the Dog," "John Q" and "Donnie Brasco."
