If you don’t want to know which Simpsons character is set to come out of the closet – stop reading now. And for those who thought it was Smithers – you’re wrong! According to reports in the US, the gay character will be Marge’s sister, Patty. A source on the show said: ‘Patty confesses to Marge that she is a lesbian and she has decided to marry her lesbian partner. Her girlfriend is someone Patty has known for a long time but has yet to be introduced to viewers. ‘But before the girls can wed, Springfield has to pass an ordinance allowing same-sex marriages. Marge throws herself into the campaign to change the law so her sister can marry – and pulls it off!’ At first, Homer finds it difficult to accept his sister-in-law is gay – but ends up walking her down the aisle.
