Justin Timberlake performs ‘Mirrors’ with Taylor Swift in Los Angeles...

Pulling out the stops, Taylor Swift had her fifth and final sold-out show at L.A.’s Staples Center last night. Justin Timberlake joined her on stage for the first time since becoming a father. 
He took a break from changing diapers to duet with Taylor on his hit song 'Mirrors.' She showed everyone just how much of a big JT fangirl she truly is and it's safe to say she wasn't the only one. Well, savour the moment because the next album from him probably won't drop for at least another 10 years, if that.
