How to create a clipping mask with an item that already has a clipping mask?

Hi all! I have a circle. I wanted rainbow-colored stripes within that circle. So I created the stripes and the circle... and created a clipping mask. No problem. But I don't know how to do the second part... which is to create a heart INSIDE the rainbow-colored circle... that's see-through. i.e., it's not white... it's clear. When I select both the circle and the heart and try to create a clipping mask... it puts the colored strips inside the heart. I want it to do the opposite. I tried using the pathfinder, too, but that didn't work at all. What am I doing wrong? Thank you!
