This photo pretty much proves Heidi Montag and Spencer Pratt aren't getting divorced ... and may also make you lose your breakfast.

The gruesome twosome just happened to be photographed while kissing on Heidi's 24th birthday in Santa Barbara yesterday -- while Montag proudly displayed her wedding ring.

A toast to the happy couple?
