Any idea the (negress?) songstress and name of this (80s) song?



"You know I love you
..cos we've been together
I realise that we can last away
boy I've been touched by your sincerity
....baby can't you see that there's no other
I'm the one for you you'll discover
now don't be suspicious
I won't ever play my games with you
I now how you're feeling
some folks what their cake and eat it too
you don't have to worry
cos I'll always be one-man girl..
I'm gonna give it to you...
baby can't you see that there's no other no no
you won't ever share me with another no no
I'm the one for you you'll discover
darling can't you see that there's no other
oooh you're so special
and I appreciate a love that's true
we've both been hurt before
so I won't make that same mistake with you
and I don't need no body else i'm so in love with you...."
