Deryck Whibley married Ariana Cooper in Los Angeles

A source told PEOPLE.com: "It was a chilled and intimate ceremony. They had a violin play at the ceremony and the music was mellow, not typical rock that Deryck's band plays, which was surprising."

Deryck's model wife wore a strapless ball gown for the occasion which she opted to match with a pair of custom-made Converse trainers, while Deryck ditched his usual punk attire for a classic black suit and tie.

The wedding ceremony marked a remarkable turn around in Deryck's life after he admitted earlier this year to feeling "lucky to be alive" following a week in intensive care with severe liver and kidney problems brought on by "hard boozing".

The 'Fat Lip' singer said: "The doctors said I was lucky to be alive and that there was still a chance I could die. I do look back and think about how much worse it could have been.

"I could have had way more health problems than I had, but my liver is fine! Everything shut down before any more damage could happen. To walk out of there alive, without cirrhosis or needing transplants, you know, it could have been worse."

At their nuptials Deryck and Ariana toasted their marriage with non-alcoholic apple cider.
