Heidi Montag and Spencer Pratt have fuelled rumours of a possible reconciliation after the estranged couple was pictured together at the Avon Walk for Breast Cancer, in Carpinteria, near LA. Montag filed for divorce in July citing irreconcilable differences. Pratt then threatened to release their personal sex tapes to the media but then apologized for his inappropriate behavior earlier this month. This supposed reunion comes in the wake of Pratt’s arrest in Costa Rica for illegal weapon possession.
