The Best Damn Thing (Deluxe Version) Album • Avril Lavigne • 2007

The Best Damn Thing is the third studio album by Canadian singer Avril Lavigne. It was released on 11 April 2007, by RCA Records. The album represents a musical departure from her earlier studio album Under My Skin (2004), which incorporates more elements of post-grunge music. The Best Damn Thing is seen by critics as Lavigne's most commercial effort. The album was noted as her first effort to feature a wide range of producers, including Matt Beckley, Rob Cavallo, Dr. Luke and Lavigne herself, who was credited as the executive producer.

Upon its release, The Best Damn Thing received generally positive reviews from music critics, who praised Lavigne's transition from grungey alternative rock music to more pop-punk and bubblegum pop music, with it being catchy and very radio-friendly. However, the main criticism of the album was the lyrical content, which some found too rough or brutal. The album debuted at number one on the US Billboard 200 with first-week sales of 289,000 copies. The album also debuted atop the charts in Austria, Canada, the United Kingdom and many other countries. Alternative Press listed it as one of the albums that best represented the pop-punk scene in 2007.

The Best Damn Thing had sold 9 million copies worldwide as of 2018, it was Lavigne's third best-selling album. Four singles were released from the album. Its lead single "Girlfriend" peaked at number one on the US Billboard Hot 100, making it Lavigne's most successful chart single to date. The single also reached number one in twelve other countries across the world including Australia, Canada and Japan, making it one of the best-selling singles of 2007 worldwide. The second and third single of the album, "When You're Gone" and "Hot" were moderate hits worldwide, with the former reaching number 24 on the US Billboard Hot 100. Last single "The Best Damn Thing" reached the lower end of the charts. To promote the album, Lavigne performed at many TV shows and award ceremonies, including the 2007 Teen Choice Awards and the 2007 MTV Europe Music Awards, as well as a musical guest on Saturday Night Live.
