Bob Marley One Love video. Who are all the cameos in it?

We recently watched the video One Love by Bob Marley. I can only recognize Sir Paul in the video...can anyone tell me who else is in it? Thanks!

I read on another site that a very young Naomi Campbell was in the video somewhere, and also his son; however, other sites suggest the young boy in the video is not his son. But you can go to the source link and it will take you to a page where you can ask questions about Marley's life, music, work, etc. Hope this helps.
