What is the song that goes like this?

At the beginning it goes like this: "Ooh, baby girl, what 'cha doin' to-night, I wanna see what ya got in store ... Givin' it you're all when you're dancin' with me, something something something something somethin ... You can be my girl, I can be your man" and I don't know the rest. Also, it goes "Ooh, baby baby, la la la la la la laa Ooh, baby baby, la la la la la la laa" over and over again. At the very end, it goes "I want, you, to-night.
