SOBBING MELANIE BRINGS STING’S CONCERT TO A HALT

This news shocker screams “DÉJÀ VU!” In a tragic public meltdown, Melanie Griffith sobbed hysterically when her gumdrop-size engagement diamond from hubby Antonio Banderas suddenly vanished into thin air at a Sting concert — an incredible coincidence, considering it comes just one week after my world-exclusive about Lisa Marie Presley briny deep-sixing her $65,000 sparkler from Nic Cage! In “Hollywood’s Disappearing Diamonds 2,” Melanie shook her booty and waved hands to the beat at pal Sting’s concert in Cannes — then suddenly screamed, “OHMIGOD! My DIAMOND!” The ring Antonio had slipped on her finger in 1996 was still there — but the stone had flown its setting! Frantic Melanie fell on hands and knees, searching desperately as concert-goers rushed to help. Onstage, Sting got the word, stopped the music and ordered house lights up — but the search turned up zipp-o! Devastated Melanie — tragically reminded that even diamonds aren’t forever — exited the concert hall in tears!
