Beautiful R'n'B (Late 80's\Early 90's - Female Vocal)

I very need your help, to ID this very beautiful one...

I trying to use Google, and find some lyrics, but unfortunately without any success... :(

So... any ideas or clues are welcome!

This sounds like Carly Simon too me

Meltdown, thank for a clue. But I don't think so... I have listen many Carly Simon albums, and I don't found nothing like this...

I must sure, that is a CLEAN R'n'B from late 80's. I have many other tunes like this from the same period.

So, any other clues or ideas?
