Avril Lavigne's Ex-Husband Deryck Whibley Drops <em>Her</em> Last Name 3 Years After Divorce
Deryck Whibley is no longer Deryck Jason Lavigne Whibley.
Three years after he finalized his divorce from Canadian pop star Avril Lavigne, who has since remarried Nickelback frontman Chad Kroeger, Whibley filed a petition to legally drop her last name. He had adopted the surname as one of his middle names after they tied the knot in 2006, reports TMZ.
