Sum 41 frontman Deryck Whibley has returned home after spending more than a month in hospital.

The rocker stunned fans recently when he went public with his health battle, revealing he almost died after his liver and kidneys collapsed following years of alcohol abuse.

He further shocked devotees when he was photographed looking extremely frail as he took a walk around a Los Angeles neighbourhood, assisted by his fiancee Jocelyn Aguilar and a friend.

Now Whibley has reached out to fans once again to express his gratitude for the outpouring of support following his health crisis.

The 34 year old, who was briefly married to Avril Lavigne, shared a new photo of himself back at home on his official website, alongside the message: "hey everyone, i just wanted to thank you all so much for sending gifts and all of the compassion and support you have shown me. it really means a lot to me in this time of recovery.

"I will be better soon and back out on stage before you know it."
