Do you want a personalized “Happy birthday” from Dorian Yates? It’s yours for a hundred bucks. Cameo is the shout-out app via which you can buy short messages—well wishes, advice, motivation, etc.—from the famous, the used-to-be-famous, and the nearly-famous. What’s interesting about Cameo is the celebs set their own prices (Cameo takes 25%), providing insights into cost and demand. Caitlyn Jenner, at $2500, is priciest. Around $500 seems to be the sweet spot for big names: Snoop Dogg, Bret Farve, Troy Aikman, Mariano Rivera, Kareem Abdul Jabbar, Ice T. There are bargains, including Dwight Howard ($250), Ed Asner ($100), and Taye Diggs ($75).

The Barbell culled through the notable bodybuilders, strength athletes, and fitness personalities and ranked them from most to least expensive. As an inexact way of measuring their sales, we’ve included their number of reviews. It’s estimated that 5-10% of all online customers leave reviews, but note that some of these Cameoers may have recently joined the service. There are some surprising bargains, like 7-time Olympia 212 champ Flex Lewis ($30) and 4-time World’s Strongest Man Zydrunas Savickas ($20). And check out the off-the-chart review tallies for popular YouTubers C.T. Fletcher and Kali Muscle.
