Socialite Trump has been fending off rumours of a break-up since early November (08), insisting reports of Italian Rubicondi's infidelity were "totally false".

But now the 59-year-old has admitted her nine-month union is over - confessing she filed for legal separation three months ago.

And she blames their differing lifestyles for parting from her 35-year-old beau.

In a statement issued on Monday (01Dec08), she says, "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!'"

Rubicondi was Trump's fourth husband. They dated for six years before exchanging vows in April (08).
