"Taylor Swift duetted with Jennifer Lopez in Los Angeles last night (August 24). The &amp;#039;I Knew You Were Trouble&amp;#039; singer brought Lopez out during her concert at the Staples Centre to perform a special rendition of &amp;#039;Jenny from the Block&amp;#039;.      &amp;quot;I don&amp;#039;t know about you but when I was a little girl... you know how you have your favourite song that you just play over and over again?&amp;quot; Swift asked the crowd before introducing Lopez. &amp;quot;You just blast it in your room and sing in front of your mirror into a hairbrush. You had that one favourite song that was your favourite to dance to. Los Angeles, this is my hairbrush song.&amp;quot; Lopez then appeared on stage to huge cheers from the audience before singing the 2002 hit. Swift duetted with Ellie Goulding and Cher Lloyd during her other shows at the Staples Centre last week. "^^<http://www.w3.org/2001/XMLSchema#string>
