BRIDE-TO-BE GIVES DiCAPRIO THE HEAVE-HO

Man the lifeboats . . . it’s a TITANIC disaster!

Leonardo DiCaprio and fiancee Gisele Bundchen’s loveboat just hit the rocks and sank like a stone . . . so it’s buh-bye church bells and slam down that organ cover — this wedding is definitely OFF! After one year together, Gisele suddenly threw Leo overboard when he blew off her special plan for them to spend a romantic weekend — and jetted off to Las Vegas with his buddies! Gisele had arranged to do a Victoria’s Secret photo shoot in LA, Leo’s hometown, so they could get all snuggly-wuggly together — then flew into a RAGE when Leo blithely announced he and pals were going to Vegas for the Lewis vs. Rahman boxing match — and she was NOT invited! Leo told Gisele she was making a mountain out of a molehill — that he’d return home right after the fight. But when he did, he found a note that read, “It’s OVER!” Gisele’s telling pals she suddenly realized that if Leo likes partying with his buddies so much now, what would married life be like?
