The devolution of Tegan and Sara from cool indie lesbians to Liz Phair-esque pop stars officially occurred Tuesday night in Los Angeles, when Taylor Swift had the duo perform their single "Closer" during one of her shows.

"If you've ever had your heart broken, you need to have their album," said Taylor in her one-line back cover review of their music. Tegan and Sara sound great and if you enjoy watching Taylor Swift dance in hot pants, you'll like this performance.
