PARTYING STAR SHOCKS PALS WITH ITCH TO GET HITCHED

LEO BE WACKY-O!

I don’t believe rumors that pals are now calling him “Leo Be Wacky-o,” but . . . Leo DiCaprio and off-again-on-again model squeeze Gisele Bundchen stunned pals while partying in Las Vegas by suddenly announcing in the wee hours: WE’RE GETTING MARRIED! Believe it or not, Leo initiated the dizzy idea of a quickie Vegas-style hitch — and Gisele giddily insisted on an Elvis impersonator to perform the ceremony! Horrified friends pulled Leo aside, argued that zip-splicing’s ALWAYS a bad idea — AND reminded him that he and Gisele have had a VERY rocky relationship! When the couple realized their pals were genuinely shocked, they suddenly dropped the idea. (WHEW!)
