Ivana Trump and her 4th husband, boytoy Rossano Rubicondi have split ending much speculation that their marriage was in trouble.  Ivan filed for legal separation 3 months ago.

The 59 year old Ivana blames differing lifestyles with the 35 year old Rossano:

“Rossano wants to live in Miami (Florida) and work in Milan But, I am a New Yorker and my family, friends and businesses are here As the beautiful song says, ‘Que sera sera!’”

She seems really choked up over this, no?  I guess after 4 you get used to the split and can keep emotions in check, right??  lmao….okay I crack myself up.  No disrespect.  They dated for six years before exchanging vows in April, 2008.
