Collen, the guitarist from the rock band Def Leppard, wed costume designer Helen L. Simmons on a beach at the Ritz-Carlton, Palm Beach in Florida, People magazine reported. Guests at the ceremony included Def Leppard members Rick Savage and Vivian Campbell.
The bride was adorned in an Adele Wechsler gown, while the groom wore a J. Lindeberg suit.
Both Collen, 52, and Simmons, 42, met during Def Leppard’s "Sparkle Lounge" tour two years ago.
"We've been looking for each other our entire lifetime," Collen told the magazine. "To say we're ecstatic this day has finally come is putting it mildly. It could only be us for each other."
The wedding also incorporated some environmentally-conscious flourishes, including e-mail invitations and a vegetarian and vegan menu at the reception.
"We didn't intentionally start out trying to have green wedding," Collen said to People. "But since it's a natural part of our lifestyle to respect the environment, everything flowed pretty naturally."
Collen joined Def Leppard for their 1983 album "Pyromania," that contained the hits “Photograph,” “Foolin’” and “Rock of Ages.”
As far as Def Leppard’s future plans, lead singer Joe Elliott told Billboard.com that the group was assembling a live record from a tour last year.
