Liza Minnelli tied the knot for the fourth time in the wackiest showbiz wedding ever!

The groom wore makeup ... Liz Taylor forgot her shoes ... Robert Wagner wandered into the ladies room ... Joan Collins dissed David Hasselhoff ... and Pee-wee Herman wore pink tights!

But the bizarre antics kicked off two days before the March 16 nuptials -- when three Judy Garland impersonators greeted groom David Gest at his bachelor party!

The issue on sale now features exclusive ENQUIRER photos of the $500,000 wedding, including blushing bride Liza in her dazzling designer wedding gown, the star-studded guest list -- and much, much more!
