It's official!
Sum 41 singer Deryck Whibley said "I do" to longtime love Ariana Cooper during an intimate ceremony at the Hotel Bel Air in Los Angeles on Sunday.
Whibley's mom posted a shot via Instagram of the newlyweds toasting on their special day. "A toast to the bride and groom Mr & Mrs Whibley #whibleywedding," she captioned the sweet snap.
"It was a chill and intimate ceremony," a source close to the couple told People about their weekend nuptials. "They had a violin play at the ceremony and the music was mellow, not typical rock that Deryck's band plays, which was surprising."
Ariana looked stunning wearing a strapless white beaded gown. She styled her hair in a classic updo and finished her wedding day look with white Converse sneakers.
"She had the coolest kicks in town," the pair's wedding planner Christine Zohrabians posted on Instagram with a shot of the brunette beauty's custom shoes.
While it's been a rough year for the rocker -- who was rushed to the hospital in 2014 after experiencing organ failure from years of alcohol abuse -- it looks like Deryck is doing better than ever these days.
This is the second trip down the aisle for Whibley, who was married to Avril Lavigne from 2006-2010.
