Estranged couple Heidi Montag and Spencer Pratt have fueled rumors they have reunited after they were spotted publicly kissing.
Montag filed for divorce from Pratt in July citing irreconcilable differences, and her former "The Hills" co-star subsequently threatened to release sex tapes featuring his former partner.
But earlier this month Pratt reached out to his estranged wife to apologise for his behaviour and the pair sparked reports they have reunited by embarking on a charity walk together on Sunday.
Now it seems the divorce has been called off - the reality TV stars were photographed in Santa Barbara, California kissing on Montag's 24th birthday on Wednesday, while her wedding ring was clearly visible.
