With so much reality TV on the air, it’s no surprise that shows have wound up recycling celebs. But which stars keep coming back for more and more punishment? Which have signed on to project after project? Which have actually clocked the most reality shows?

These stars have all appeared on at least four or more shows, and will undoubtedly do many more in the years to come. Call them reality whores—ready to sacrifice their private lives for your entertainment, again and again.
