Help identify this song please!

So what I know about the song is this: it is a relatively new song (2008 / 2009) that is sung by a Pop Girl group, similar to the ***** Cat Dolls. I know the lyrics below are probably not correct but it goes something like: It's madness, madness (in harmony) the way you're making me feel... And that's all I really know. Not much to go on, I know, but any help would be greatly appreciated.

Some additional help, the tempo to the song reminds me of the song So Dangerous by Akon, with that Pop / R&B feel to it.


Thank you!
