Taylor Swift And Avril Lavigne Proved There's No Bad Blood With A 'Complicated' Duet

Things aren't so "complicated" after all!

Both Taylor Swift and Avril Lavigne adore their fans, and they're not afraid to show it -- together.

After some awkward Twitter drama this week when a fan of Taylor's indirectly accused Avril of not giving her fans enough love during meet and greets, the two pop stars came together in the best way they know how -- by appearing on stage hugging one another during Taylor's 1989 World Tour in San Diego.

Even better? They also sang Avril's hit song "Complicated" to a stadium of screaming fans. Be still my skater girl heart.

"Such a Pleasure to perform "Complicated" tonight with @taylorswift on her #1989 world tour! She ROCKS ???" Avril wrote on her Instagram last night, adding, " She is a Doll ?????? Thank you Taylor for having me up on stage and thank you San Diego ???? #Complicated #Grateful."

Taylor agreed, saying of Avril on Twitter, "'Complicated' is such a brilliant pop song and I just love her," and on Instagram, "Taylor hearts Avril. ?"

Now, can these two collaborate on an album together? Because that would be amazing.
