Sum 41, Avril LavigneA year and a half after his divorce from pop-punk princess Avril Lavigne, Sum 41 singer Deryck Whibley says that, despite their former "irreconcilable differences," the two still remain friends.

"We're on good terms now," Whibley tells PopEater about Lavigne, whom he married in 2006. Their divorce was finalized last November after a yearlong separation, and Lavigne is currently dating Brody Jenner of 'The Hills.' "I even produced some of the songs on her new album."
