Ah, yes, that song definitely brings back nostalgic feels for us and we wonder if the Jingle Ball Chicago crowd felt the same!
Avril Lavigne took the crowd back in time at 103.5 KISSFM's Jingle Ball!
The punk princess performed a couple of her classic hits like Complicated and Girlfriend!
Okay, well, they're not THAT old, but they do take us back to the early 2000s! Lolz!
Ch-ch-check out the videos of Avril performing her classics (below)!!
