The Selena Gomez, joined Swift on stage at LA's Staples Center, where the pair then sang JB's hit tune, Baby.
Once they had stepped of stage, Taylor took to Twitter to tell her followers about her duet with the Biebster, tweeting: "You think you've heard LOUD screaming in your life.T hen @justinbieber comes out and does a surprise song during your show. Woah. Unreal."
The 17-year old teen heartthrob then responded to Swift's tweet, writing: "@taylorswift13 we should do that more often. :) great show! #muchlove"
Since performing together, fans of both Taylor and Justin have urged the duo to collaborate, with one Twitter user stating: "Taylor Swift and Justin Bieber should do a song together."
Biebs' supposed ex-girlfriend Selena recently praised Swift, telling Top Of The Pops magazine that in the past, they have helped each other through relationship break-ups.
We wonder what Gomez would make of Taylor's new found friendship with Justin?
