Dude, you're right. She's awesome. Some of the girls in those older wet t-shirt contest videos were...whew!
Anyways, you might want to try EMX:

In the lower left is a button that says "submit form." Push it (no need to enter your information in the blanks). That will take you to EMX's free content page. Click on "Public Nudity Movies" and you will be transported to a wonderland of free samples from wet-t, club, spring break, etc. videos. They've got a few Dreamgirls selections--and a ton of other stuff just as good.
Have fun. nobus
