Heidi and Spencer -- Reunited and it Feels So Bad

Heidi and Spencer, please ... just divorce already. We got these photos, which were taken yesterday just north of Los Angeles, and the rat we're smelling is really beginning to stink.


Although Heidi insists she's divorcing Spencer, they were walking in stride in Carpinteria, CA at the Avon Walk for Breast Cancer.

Spencer is fresh off his arrest at the airport in Costa Rica, after he was snagged for illegal firearms possession, cited and released.

If these crazy kids can't make it work, what hope do the rest of us have?
