ELVIS Presley’s ex Priscilla was shattered when she learned her former boytoy lover Marco Garibaldi — father of her 31-year-old son, Navarone — is a fake and con man living a twisted lie! For the 22 years he lived in her Beverly Hills compound before their 2006 split, Marco, now 63, conned Priscilla, 73, into thinking his last name was the noble-sounding Garibaldi and his wealthy Italian family moved to Brazil when he was a tot, say relatives. But the shocking truth is he was born in the Portuguese-speaking nation — and his real name is Garcia. Marco changed his last name and invented a romantic story about Europe and wealth to impress Hollywood bigwigs and Priscilla after they met in 1984, say sources close to the family. Find out in this week's GLOBE Magazine how Priscilla was betrayed.
