Jill Sobule, the singer of the groundbreaking 1995 hit “I Kissed a Girl,” has tragically died. The musician and songwriter perished in a Minneapolis house fire early Thursday morning, several of her former colleagues confirmed to The Post. Sobule was 66. She became a household name with “I Kissed a Girl,” which is widely viewed as the first openly gay-themed tune to make it into the Billboard Top 20. Millennials will know Sobule for her song “Supermodel,” which was featured in the 1995 coming-of-age teen classic film “Clueless.”
