As Taylor Swift's North American tour continues, she keeps bringing out surprise guests to join her. Tegan and Sara appeared with her onstage Tuesday night at the Staples Center in Los Angeles.

Joining the ranks of Swift's previous stage companions Carly Simon and Jimmy Eat World's Jim Adkins, the sister duo joined the "Red" singer for a live rendition of their hit "Closer."

Whatever you may feel about Swift or her fans or her waist high shorts, it's kind of nice to hear and see the effusive response from the crowd when Tegan and Sara are introduced. Well-deserved love.

Speaking of love, the pair performed "Same Love" earlier this month with Macklemore at Montreal's Osheaga Festival. It was rather fantastic, in case you missed it.
