Selena Gomez hit the stage with Taylor Swift as the first surprise guest. The two ladies sang "Good For You" live for the very first time together. 

"The person about to come out onto the stage is a multi-talented performer who's good at pretty much everything that she does. She is beautiful and funny and sweet and talented and intelligent and one of my best friends," said Taylor before Selena showed up on stage. 

Next to perform with Taylor was Justin Timberlake. Like any other 90s kid, Swift is a huge fans of Justin T. Long before he became a solo artist, Justin was part of the hit boy band N'Sync.

"You have no idea. I don't even know where to start because anyone who knows me knows this is my favorite artist," gushed Swift about Timberlake before the duo sang his hit "Mirrors."

Last but not least to perform on stage was Lisa Kudrow. Taylor and Lisa sang their rendition of "Smelly Cat," which Kudrow said she hadn't performed since the hit TV series "Friends" ended. 

Taylor Swift has set a new record for the "Most Sold Out Performances" at the Staples Center in Los Angeles for her final 1989 World Tour in the City of Angels. 

By the looks of it, it is obvious that her audience totally enjoyed her 1989 World Tour. There's definitely more to come for Taylor Swift!
