"So excited to release new music !!!" the "Complicated" singer wrote in response to Barker's post at the time.

In a recent interview with The Forty-Five, the eight-time Grammy-nominated artist reflected on her 20-year music career, telling the outlet that she feels lucky and honored to still be doing what she loves nearly two decades after "Sk8er Boi" put her on the map.

"I'm really grateful to still be doing what I love and to have a musical outlet. I'm having so much fun with it all, and I guess you can tell," she shared.

"I'm not just putting out another record to put out a record, I'm making music this far into my career because I truly want to and it's just such a big part of my life," Lavigne added. "I'm so excited to still be doing my thing."
