As if Taylor Swift's sold-out Speak Now tour needed more buzz, she added a new performer to her roster – for one night, at least. Ellen DeGeneres joined Swift on-stage and they even sang a sweet duet together.
Taylor hinted that she had a surprise in store, tweeting, "Backstage getting ready to play our 4th night at Staples Center-- this should be a fun night full of surprises ;)
DeGeneres walked on stage and joked to Taylor, ""I was looking for the ladies room. I'm so sorry,"
"This has been happening quite a bit. People are just going about their daily lives and they end up on our stage," Taylor joked.
Taylor and Ellen then sang a sweet duet of Our Song together.
"Just got off the stage with @TaylorSwift13 at Staples Center," Ellen tweeted. "Our song is now 'Our Song.'"
Taylor recently was the one crashing concerts, when she caused a fan frenzy by showing up at a Justin Bieber concert and singing his hit song, Baby, with him.
Check out Ellen's surprise visit and duet with Taylor Swift – or you can tune in to The Ellen DeGeneres Show on September 14th to watch the fun unfold during her premiere week.
