"Losing Grip" is the fourth single and last single (except in Australia and New Zealand where "Mobile" was released) from Avril Lavigne's multiplatinum album Let Go. It was released in late spring of 2003 after the success of "I'm With You". The song was written and produced by Avril Lavigne and C. Magness. The song is much heavier than most of the songs on Let Go that had a more poppy feel (possibly the explanation of its weak success). Avril has stated its her favourite song on the album though. It is about Lavigne "losing grip" with her boyfriend as they are just not meant to be. "Don't Tell Me", the first single from her second album Under My Skin, is said to almost be a follow-up or part two of the song as Avril tells her boyfriend she does not want him because of his sexually-rude behavior. The single was certified Gold by the RIAA in September 22, 2003[1]. Alanis Morissette sang it, in a duo with Avril Lavigne at the House of Blues in 2005
