"Hot" was the third single, released in October 2007. The song was written by Lavigne herself and Evan Taubenfeld; it showcased Lavigne at her most revealing. The lyrics describe Lavigne's feelings for a guy who "makes feel hot". The song's music video was considered her sexiest to date at the time. The single was the least successful in the US, charting only at No. 95 on the "Billboard" Hot 100, yet it managed to reach the top 10 in Japan and Canada, and top 20 in Australia. A version of the song was recorded in which the chorus was replaced with lyrics in Japanese and Mandarin.
