DESPERADO (Alex's Bubble Bath Song???)

Hi fellow ArcAngels!
On the dvd for Season 2, (the episode is titled "Desperado"), there is a scene where Alex is taking a bubble bath. There is a slow jam playing in the background, with female vocals. These are the lyrics:

"Baby, i know you had a hard day
but i was hoping you would come over
and sit back, relax, and just lounge.
We can do whatever, whatever you want
so it's up to you, as long as when you come thru
you'll sit back relax,and just lounge..."

I have been feverishly trying to track down this track and i even contacted Patrik Ian Polk himself on his Myspace page, but to no avail.

If anyone out there can help, i will love you from afar...

Thanks in advance
