His fiancee Jocelyn Aguilar and another woman helped Whibley safely walk down the street in Los Angeles. 

The pop rocker, 34, has spent weeks in the hospital following a collapse in his home, which he believes was the result of years of "hard boozing."

"My liver and kidneys collapsed on me," he wrote on his website. "Needless to say it scared me straight. I finally realized I can’t drink anymore. If I have one drink the docs say I will die. I’m not preaching or anything but just always drink responsibly."

Whibley and Lavigne were married from 2006 to 2010, and on May 17, she tweeted her support for her ex-husband. 

"Spoke to @Sum41 Deryck today. I am so proud of him," Chad Kroeger's wife wrote. "He is family to me and always will be. #StayStrongDeryck."
