The bizarre relationship that has blossomed between a ram and a doe in China's Yunan Provincial Wildlife Park is to be recognised through holy matrimony on Valentine's Day.
Chang Mao the ram and Chung Zi the doe developed a relationship last year, but were separated by the zoo because Chang Mao had kids to look after following an indiscretion during rutting season.
People were convinced of their love when Chung Zi put an end to the separation by breaking through a fence to be with Chang Mao.
Her persistence paid off when they were reunited, and now zoo officials want to celebrate their love with a wedding on Valentine's Day.
Around 500 tickets are on sale to the public at 66 yuan each (equivalent to £6.60 or $10). The zoo has confirmed that the pair will wear "wedding clothes". They have not confirmed whether the couple will be given a cut of the earnings.
The ceremony will follow local customs, with the two being put on either side of a 'wall', which Chang Mao will have to break through to see his bride.
Considering they are reported to have been mating every day, even out of season, encouraging him to do this shouldn't prove too difficult.
They will then be led to an arch with the words "I do" written across it, where they will share a carrot to symbolise their spiritual and physical union.
Scientists have warned that it is highly unlikely that the pair will be able to have kids since they are from different species.
Although most animals don't get married, many mate for life, such as swans, gibbons, wolves, albatrosses, prairie voles, and apparently, the parasitic schistosoma mantoni worm.
