Los Angeles: Continuing her streak of inviting musical guests, singer Taylor Swift was joined by country star Keith Urban during her Toronto concert.
The pair performed a rendition of "John Cougar, John Deere, John 3:16", before Urban sang solo on one of his tracks, "Somebody Like You", reported Entertainment Weekly.
"Someone absolutely incredible is about to come out on this stage. This is someone who has sold 20 million records but, more importantly, is an amazing human being," she told the crowd.
Swift, 25, posted a black-and-white photo of her and Urban together during a sound check to commemorate the event.
"He's been so wonderful to me. He's one of the most talented people who has ever been born," the pop star added.
In 2009, Swift opened for Urban on his Escape Together World Tour, which she referenced in his introduction during the concert. The two later re-teamed for Tim McGraw's "Highway Don't Care", released in 2013.
