Rosanna Arquette at the 2006-2007 ABC Upfronts at Lincoln Center. New York City, USA - 16.05.06

THE BIG BLUE star's name is pronounced "Ro-sahn-na", not "Rose-anna".

Arquette was dating Toto keyboardist and composer STEVE PORCARO, but the song was actually written by bandmember DAVID PAICH.

She explains, "It probably sounds better in a song to sing it that way.

"A lot of people call me, Rosanna, but my mother calls me Ro-sahn-na."

The song won a Grammy Award for Record Of The Year in 1982.
