Avril Lavigne has promised fans they are going to love her "fun" new album.

The Canadian singer has revealed the title of the LP will be The Best Dam Thing and will be released in April, preceded by the single Girlfriend which is due out in February.

In a posting on her MySpace website page, Avril writes: "I promise you guys will love this record, it is my favourite one! And I can't wait. I wanted to make sure the songs were fun. Fun for the fans and myself. I will only have like 3 slow songs on the record. I am working on my last song right now in the studio. I should be all wrapped up by Monday in time for the Christmas holidays.

"The album is fast, fun, young, bratty, aggressive, confident and cocky in a playful way. All the good stuff."

The new album is Avril's first since 2004's worldwide hit Under My Skin.

In July, Avril, 22, married Sum 41's Deryck Whibley in an outdoor ceremony at a private estate near Santa Barbara.

They had been dating for two years.
