Pop-rocker Avril Lavigne is celebrating a win at the 2012 Billboard Japan Music Awards. 

The 'Wish You Were Here' songstress was named Top Pop Artist by the ceremony's bosses and Billboard.com reports that "the artists were eligible for the prize by topping one of the Billboard Japan charts, which include Billboard Japan Hot 100, Billboard Japan Singles Sales and Billboard Japan Top Albums". 

Fans were able to cast their votes via the internet and although Lavigne didn't attend the event in person, she sent over a video message and thanked her followers for their support internationally:

"I'm so happy that I was chosen for the Top Pop Artist at Billboard Japan Music Awards. Thank you so much guys for listening to my music over here in Japan."

Yesterday, March 6, Lavigne told her 4.2 million Twitter fans that she is working on new material and has been in the studio with Nickelback's frontman Chad Kroeger:

"Working hard in the studio writing, recording and raging!!!! You know it. 7 days straight- who needs a break! Ha."

"Rise and shine... studio time. 6th day in a row, having a f**king blast with Chad from @Nickelback and @hodgesmusic!!! 5 songs in."
