looking for song

not sure if its out of the 80's or 90's. but I know its a female singer. and I can't think of the lyrics I know how it sounds. I do know a male voice will go wooooo who wooooo who during breaks from chorus and vocal.

lyrics that I think mite be in it, but not sure.
'now that were together, I hope it can last for ever"
"your my world, everything, the moon and the stars"

thats all I remember
