Jeffree Star told Shane Dawson one of his Instagram posts could have been worth up to $300,000 in the third episode of "The Beautiful World of Jeffree Star."

Dawson told Star he posted a giveaway for free because he'd received two of the same eyeshadow palette from Anastasia Beverly Hills.

"Anastasia could have paid you $200,000 plus to do this giveaway," Star said. "That's how much you just... You just gave them so much free publicity."

Dawson is learning all about the beauty world as he and Star document their development of a collaborative makeup line in the series.

Star, who has been teaching Dawson about the business of the beauty world while they collaborate on a new "Conspiracy" makeup line together, looked at the camera before revealing just how much Dawson had missed out on.

"Anastasia could have paid you $200,000 plus to do this giveaway," he said. "That's how much you just ... You just gave them so much free publicity."

"Oh my God," Dawson replied in a whisper. "I could have made $200,000?"

Star laughed and said that with Dawson's YouTuber fiancé Ryland Adams also in the photo, it could have been worth $300,000.

Looking shocked, Dawson joked, "should I delete it?"

The rest of the episode focused on a first look at Star and Dawson's new collaborative palette, with all the new shades and names Dawson had picked out, including a bright yellow "Food Videos," a beige "TanaCon," and a hot pink "Trish" (an ode to Trisha Paytas).

There was also behind-the-scenes footage of the aftermath when one of Star's warehouses was robbed of $2.5 million worth of makeup in April.

Dawson began the series by candidly saying he doesn't have much of a business mind like other YouTubers, and wanted to learn more about his earning potential.
