Taylor Swift has had a few surprise guests join her onstage as part of her Reputation World Tour.
Back in June, Robbie Williams dueted with the star on stage and now Bryan Adams has done the same! The pair sang Bryan's famous song 'Summer of 69'.
A clearly excited Taylor shared some videos from their performance on her Instagram.
"I didn’t even know Bryan was gonna be in town until last night and I asked him completely last minute if he wanted to come sing!" the star wrote.
"Pretty evident from the videos (um yes I’m posting another one) that I’m FULLY LOSING IT with excitement, and I can’t thank Bryan Adams enough."
Their performance has been viewed millions of times already, with many fans saying they love the sound of Taylor's voice with this style of music.
Taylor also shared a few behind the scenes photos of her rehearsing with Bryan which you can check out below...
