This may not be happening anyway since Ivana had the fiancee thrown out of her house by the Palm Beach Police the other night...

(And, btw, how classy to invite 600 guests to your marriage to a boy toy at
her ex husbands estate!! )
Rossano trumps all previous weddings

BRIDEZILLA Alert: Ivana Trump's April 12 wedding may be her third -- but that doesn't mean the 59-year-old Czech is planning anything less than an over-the-top event to seal her union with toyboy Rossano Rubicondi, an Italian actor who is 24 years her junior.
According to staffers at Donald Trump's ritzy Mar A Largo estate, where the ecumenical ceremony is taking place, the 600-strong guest list includes the likes of Liza Minnelli, Diana Ross and Natalie Cole, as well as a contingent of 25 bridesmaids and 25 groomsmen.
Daughter Ivanka will serve as maid of honour, while sons Donald Jr and Eric will give the bride away.
Recipients of the gold-embroidered linen invitation to the event have been warned not to bring cellphones or cameras with them -- probably due to the $250,000 exclusive deal with the photo agency Getty Images.
Male guests are being asked to wear head-to-toe white (yes, P-Diddy-style) while female guests have been requested not to wear the colours pink and yellow -- the dominant colours of Ivana's six dresses for the day -- and instead to stick to "solid pastel long gowns".
