Are Heidi Montag and Spencer Pratt headed toward reconciliation?

The estranged couple celebrated Heidi's 24th birthday at the Santa Barbara Zoo with a kiss, two glasses of champagne and a few of their paparazzi friends to take the photos.

According to PEOPLE, they also had dinner on a pier in Santa Barbara.

Back in June, the reality starlet filed for legal separation from her husband. On July 30, she moved ahead with divorce papers, with Spencer himself filing for divorce in August.

Montag then moved to Costa Rica, where Pratt followed her recently.

The pair just returned to the States, but not before Spencer was arrested for possession of a firearm.
