So I think the track I'm after is from the 80s or first part of the 90s and has a female vocalist and the chorus is like

"Whoa oh, she's got a secret,
And something to hide"

I dunno, maybe I'm way off on the lyrics but I think that's how it goes.

Its an uptempo pop/rock groove. Been years since I heard it but used to be played fairly often on the radio so I don't think its super obscure.

Any help appreciated.
