"I can't slow down, because I don't know how" .. what song is that??

I heard it on a radio and the only line of lyrics I remembered were those. I think the song is older but made into a dance remix. The singer was female and it sounded like the chorus said something like "give it a chance" but when I looked it up I couldn't find it.

HELP PLZ!

wow...i can't think of it, sorry
