Selena Gomez and Taylor Swift are all about helping each other out — on and off the stage.
The BFFs hit the stage at Swift’s latest show from her "1989" tour at L.A.’s Staples Center for a duet of Gomez’s new single “Good For You.”
Swift, all supporting her bestie, called it “the song of the summer.” They sported inverse ensembles: a custom white bustier and tight shorts for the “Blank Space” singer, and a plunging top and black shorts for Gomez, with knee-high boots.
“After nearly 8 years of friendship, I just can't wait to tell our kids we ACTUALLY got to perform in front of thousands of insanely beautiful people together," Gomez wrote on Instagram after the show. "TWICE! I love you Tay. #bestnightEVER #whatISlife."
Swift, who has invited the likes of Cara Delevingne, John Legend, Julia Roberts, Chris Rock, Ellen DeGeneres and Alanis Morissette to join her during her tour, also had Lisa Kudrow and Justin Timberlake at Wednesday night’s concert.
Kudrow and Swift performed a duet of the “Friends” famous hit “Smelly Cat.”
“Never thought I'd say this but "Smelly Cat" was on my set list last night. @LisaKudrow, you are the greatest,” Swift tweeted after the show.
