Boyfriend/girlfriend song?

[mully]

 I remember a song it was by a man and a women singing to each other -the words that i can remember go something like

" thats my girlfriend" then the girl would reply "thats my boyfriend"  those are the only words that i can think of it was a hip hop song

-would like to know who sang it and what the title was?

thankyou

I think the song you're thinking of is by Blackstreet and Janet Jackson and I think it's called Boyfriend/Girlfriend
