Helen Hunt and Matthew Carnahan split after 16 years together

After 16 years together, Helen Hunt and Matthew Carnahan have called it quits.

"They had a rocky relationship and many offs and ons over the years," a source told E! News. "They stayed together as long as they did because of their daughter. They've split up before, but this time seems to be different."

The actress, 53, and her writer-producer ex, 56, share a daughter, 13-year-old Makena.
