Avril Lavigne may be turning 29-years old today, but it looks like she's never growing up!
The Canadian pop star first found fame with her hit single "Sk8er Boi," and since then she's continued to dominate the charts with her music and the runways with her Abbey Dawn clothing line.
With two new songs on the radio -- "Here's To Never Growing Up" and "Rock N Roll" -- Avril's definitely maintained her superstar status through the years.
Avril's also had an exciting love life! In 2006, Lavigne said "I do" to Sum 41 frontman Deryck Whibley, but the two finalized their divorce in 2010.
The singer briefly dated "The Hills" star Brody Jenner thereafter, before falling head-over-heels for Nickelback crooner Chad Kroeger while the two were working on her latest studio album.
In July, the musicians tied the knot in a ceremony fit for rock stars which was held in the South of France -- and in true punk rock fashion, Avril wore black for her big day!
The "Let Go" singer seriously looks like she hasn't aged a day since she first hit the scene -- see how more of your favorite pop stars have fared through the years by clicking "Launch Gallery" above!
