Sum 41 lead Deryck Whibley has been dealing with a lot of big life changes. Most recently, he’s finally received a legal name change, dropping the last name Lavigne that he acquired when he married ex-wife Avril Lavigne.

The 34-year-old rocker married the ‘Hello Kitty’ star in 2006 and officially changed his name to Deryck Lavigne Whibley. The forward-thinking couple only lasted for a few years before they filed for divorce in 2009, but it wasn’t until this past November that Deryck went through with the paperwork to drop his last association with the blonde singer. The change was approved this past Thursday, June 12, according to TMZ.

Deryck has also been struggling with alcoholism and just last month spent time in the hospital due to medical issues resulting from the addiction. On June 6 he posted an update on his health to his website, sharing, “My days are quite full, but I work on getting better every day. I have doctor check ups often, and I’ve had so many needle pricks in the past few months, that all the veins in my arms are dead. … The progress may seem slow to some people but I’m getting better all the time and I love being sober.”

On a happier note, he added, “There’s a lot of writing going on as well and I have a few exciting things for a new record already. I can’t wait to get back out there and see you all again.”

We're wishing you the very best on your recovery, Deryck!
