Heidi Montag and Spencer Pratt Reunite (PHOTOS)

Heidi Montag and Spencer Pratt are supposed to be divorcing – but instead they were snapped kissing at the Santa Barbara Zoo in California on Wednesday.

After splitting, publicly bashing each other and allegedly orchestrating the release of their sex tape, the formerly estranged pair appears to be back on (or at least pretending to be). The two were snapped clutching champagne and toasting Heidi’s birthday. Spencer did apologize this week; perhaps Heidi accepted.
