"We've been looking for each other our entire lifetime," Phil Collen tells PEOPLE of his costume designer bride

Love Bites? Well, not for Def Leppard lead guitarist Phil Collen.

The British rocker married costume designer Helen L. Simmons on the beach at Florida’s Ritz-Carlton, Palm Beach resort in a sunset ceremony Friday.

“We’ve been looking for each other our entire lifetime,” Collen tells PEOPLE. “To say we’re ecstatic this day has finally come is putting it mildly. It could only be us for each other.”

Guests included Collen’s Def Leppard bandmates Rick Savage and Vivian Campbell, as well as Muay Thai champion and trainer Jean Carrillo, who served as best man.

The couple, who met on the band’s 2008 Sparkle Lounge tour, also added some environmentally friendly touches to their big day.

“We didn’t intentionally start out trying to have green wedding,” says Collen, 52. “But since it’s a natural part of our lifestyle to respect the environment, everything flowed pretty naturally.”

They e-mailed their invitations, which were designed by Paperless Post, and their alcohol-free reception meal featured an organic vegetarian and vegan menu since Collen has been meat-free for 27 years.
