Taylor Swift may be famous but she still fan girls just like us. Keith Urban was performing at the Washington State Fair when he surprised the crowd with the cover of Taylor's new song, "Lover." Keith shared a clip of the cover on Instagram with the caption: " Every now and then you hear a song that you love and wish you'd written... and a HUGE thx to my band as well - we didn't get to rehearse so... this is us fully winging it!" When Taylor saw the post she immediately responded on Twitter saying" My heart exploded into confetti hearts, Thank you!"
