Sum 41 frontman Deryck Whibley is cutting the final link between himself and ex-wife Avril Lavigne.
According to E! News, court documents reveal that he's ready to drop her last name. The rocker is asking to officially be known as Deryck Jason Whibley again rather than Deryck Jason Lavigne Whibley.
Lavigne filed for divorce from Whibley back in 2009 after they tied the knot in 2006. She's since married Nickelback frontman Chad Kroeger, while Whibley is dating long-time girlfriend Ari Cooper.
