Avril Ramona Lavigne

In September 2010, Lavigne's third single from her debut album, "I'm With You", was sampled by Rihanna on the track "Cheers (Drink to That)", which is featured on Rihanna's fifth studio album, Loud. In August 2011, she was featured in the music video for Cheers (Drink To That). "It's exciting to me because that was always one of my favorite songs, and for it to come out 10 years ago and so now to have it sampled and back out on the radio is pretty dope". In December 2010, American singer Miranda Cosgrove released "Dancing Crazy", a song written by Lavigne, Max Martin and Shellback. It was also produced by Martin. On 23 September 2011, Lavigne appeared in the Hub network show Majors & Minors as a guest mentor, alongside other singers including Adam Lambert and Leona Lewis. About the show, Lavigne stated, "I sang for them, and they performed for me. I was just blown away. I got to talk to them about music and the music industry, and they were all just so excited".
The release dates for Goodbye Lullaby and its lead single were pushed back several times. In response to these delays, Lavigne said, "I write my own music and, therefore, it takes me longer to put out records 'cause I have to live my life to get inspiration", and that she had enough material for two records. In November, Lavigne was featured in Maxim, where she revealed that Goodbye Lullaby took two and a half years to complete, but she cited her record company as the reason for the album's delays, stating that the album had been completed for a year. Goodbye Lullaby was released on 8 March. The lead single, "What the Hell", premiered on Dick Clark's New Year's Rockin' Eve on 31 December.
• 2011–present: Fifth studio album
Three months after the release of Goodbye Lullaby, Lavigne announced that work on her fifth studio album had already begun, with eight songs written so far. The new album will musically be the opposite of Goodbye Lullaby. Lavigne explained, "Goodbye Lullaby was more mellow, but the next one will be pop and more fun again. I already have a song that I know is going to be a single, I just need to re-record it!" Later, in July 2011, Lavigne revealed the title of two of the songs from her fifth album as "Fine" and "Gone". The tracks were originally recorded for Goodbye Lullaby but never made the final cut. It has also been confirmed that Lavigne is working with music production duo The Runners on the upcoming album.
