Taylor Swift and Ed Sheeran brought the house down at KIIS FM’s iHeartRadio Jingle Ball concert at the Los Angeles Forum on Friday.
The 27-year-old singer, dressed in black shorts and a festive gold oversized shirt, was joined by her bestie during her six-song set to perform "End Game" live for the first time.
The annual holiday event marked Swift's first big show in 10 months since her pre-Super Bowl concert in February -- though Sheeran played coy about his duet with Swift ahead of the show.
"Who knows?" he replied to ET's Keltie Knight, when asked if they'd perform the song, adding: "There will be a music video for it."
