Make sure to click on the tabs to the right to see a whole lot more.
Jose Canseco recently joined (lol), though he's not listed under "Athletes" for some reason.
Kathy Griffin is available, which shows how things have been going for her ever since the Trump beheading photo.
I actually saw one of these posted by a Facebook friend. What's really stupid is that it says cameo.com on the side, so you look like a chump who paid a celebrity to make a video for you. It would be much better if the video didn't have a watermark, and you could masquerade like you and the celebrity are friends.
They all charge different prices. Gary Payton wants $500, but Jose Canseco will do it for a mere $150: https://www.cameo.com/josecanseco
What's sadder? The once-multimillionaire celebrities resorting to this, or the people buying these videos?
