In an appearance on "The Late Show With David Letterman" last month, Anne Heche slammed estranged husband Coley Laffoon as "a lazy ass."

And she doesn't regret it one bit.

"You know, you go on Letterman to have fun and to be funny," Heche, 40, told Usmagazine.com at the Entertainment Weekly/Women in Film Pre-Emmy Party in Hollywood Thursday.

"Hopefully it was funny!" added Heche, who shares custody of a 7-year-old son, Homer, with Laffoon.

Laffoon, who received a big settlement from Heche after their 2007 split, was not amused. He told Us exclusively that he was "disturbed."

Heche is currently dating former "Men in Trees" costar James Tupper, with whom she has a 6-month-old son, Atlas.
