Taylor Swift's Duet With Avril Lavigne Is Wonderfully 'Complicated'

Our inner 13-year-olds are giddy with excitement.

Taylor Swift and Avril Lavigne may have found themselves in the middle of a (tiny) Twitter gaffe last week, but on Saturday night they put it all in the past, proving there's no bad blood between them. 

The Canadian singer took to the "1989" world tour stage in San Diego to perform her hit "Complicated" with the pop megastar. Of course, the 13-year-olds inside us were giddy with excitement. The only thing missing was Avril's plaid tie and studded belt. 

Swift also brought OMI to the stage to perform his hit "Cheerleader." She shared her excitement about the performance on Instagram with a photo and the caption, "Just casually cheerleading with @omi tonight. What an awesome guy and incredible artist."
