The blond beauty took to Twitter to share a behind-the-scenes video from her epic concert week in Los Angeles, where she performed four sold-out shows at Staples center with five special guests as part of her current Red tour.
"Staples memories. Starring @CherLloyd@teganandsara @elliegoulding @SaraBareilles @JLo #REDtour," she captioned the YouTube clip on her social media page.
The video features footage of Cher Lloyd, Tegan and Sara, Ellie Goulding, Sara Bareilles and Jennifer Lopez performing with 23-year-old songbird and also features commentary from the performers, who reveal what it's like to share the stage with Miss Swift.
"It's just a bit crazy because I'm the silly British girl that came to America and just performed with Taylor Swift," Cher Lloyd says, still a bit starstruck after belting out the lyrics to her hit "Want U Back" beside the singer.
The clip then cuts to Bareilles taking the stage with Swift, who's sporting a black pair of hot pants and a sparkly shirt, as the twosome sing "Brave" together while the audience waves their arms in excitement.
Next up is Tegan and Sara, who admit performing with the pop star was "really nerve-racking," but of course, the crowd was overjoyed by their surprise appearance.
"She was like, 'Be prepared, there's going to be lots of screaming and lots of excitement' and she has this ease…she really leads a group well," the duo noted.
The video also features footage from Ellie Goulding's performance with the "I Knew You Were Trouble" singer, and the twosome appear to be having a blast onstage.
"I just performed my song 'Anything Could Happen' with Taylor Swift. Yep, just a normal day," Goulding says before adding, "She's awesome, she's an inspiration and I can't thank her enough for letting me do this because it's been really good."
Last but certainly not least is Jennifer Lopez, who dueted with the performer on her hit "Jenny From the Block."
"Thank you so much for allowing our family to come and be a part of your family," J.Lo says while huddled in a circle with her arm wrapped around the country crooner. "To create a beautiful moment, thank you, Taylor, for being so gracious and beautiful and loving me enough to have me be here tonight. I feel very blessed to be able to share the stage with you, and I just hope that everybody has the best show that they could ever have."
