Jon Bon Jovi gave love — the official, matrimonial, hopefully lasting kind — a good name Saturday when he walked a fan down the aisle in Las Vegas.

Aussie Branca Delic tied the knot with Gonzalo Cladera in a blaze of garland-bedecked glory (yes, we’re gonna keep going with this) when her rocker idol answered her Facebook and website ( prayer. Bon Jovi was in Sin City performing a show as part of his Because We Can tour.

On her Web page, Delic, 34, pleaded, “We’re begging you … make this wedding happen. There is plenty of time in the afternoon for you to come and walk her down the aisle before the show. We’re living on a prayer and we want you to come lay your hands on me and walk me down the aisle!”

And he was there for her, in jeans and white button-down shirt. The bride wore white and carried a black bouquet. And, of course, Elvis (or one of his many doppelgangers) officiated at the Graceland Wedding Chapel, where Bon Jovi said “I do” to high school sweetheart Dorothea Hurley in 1989.

And, thankfully, the carpeted aisle didn’t look slippery when dry.

The New Jersey legend tweeted effusive kudos: “Congratulations @branksd! May you & Gonzalo have a lifetime of happiness, love & memories together – ALWAYS!”

And judging from her gobsmacked grin and sweet tweet, Delic was smitten with her impromptu usher: “@BonJovi thanks, Jon. You’re an amazing human being for taking the time with us. See you in Sydney #championbloke”
