AceShowbiz - Donald Trump's "The Apprentice" put a lot of concern on contestants' health. According to a new book by Variety co-editor-in-chief Ramin Setoodeh, the reality show required hopefuls to undergo a lot of tests, including STD test.

In his new book "Apprentice in Wonderland: How Donald Trump and Mark Burnett Took America Through the Looking Glass", Setoodeh claims that Trump is a famous germaphobe. However, it was Burnett, who served as the show's producer, who was the one who was actually concerned about the possibilities of the contestants having on-set hookups.

"[He] wanted to make sure he wouldn't be held legally liable for anything that was shared after the boardroom closed for the night," Setoodeh reveals.

"The Apprentice" alum Bowie Hogg, who appeared in the first season, told him, "It was a funnel that they stick in there." He further recounted, "Not to be crude, but they inserted it in your penis and they turned it and scraped it and pulled it out. And it was the most painful thing I've experienced in my whole life."

The decision doesn't seem to be an exaggeration. Trump's son Donald Trump Jr. and Danity Kane star Aubrey O'Day, who appeared in season 5 of the show, had an affair while he was married to ex-wife Vanessa Trump.

"I love him. Love, loved, love. I'll always have love for him," the singer said of former POTUS' eldest son. "But I saw him choose a life that was inauthentic - for status, power, whatever it is. I'm so disappointed in what he became," she said in an interview. She added that the breakup was "very hard."

"The Apprentice" wasn't the only TV show who required its contestants to undergo STD tests. Contestants on "The Bachelor" also must take STD tests before joining the show.

It was also revealed back in 2018 that stars on Bravo's reality shows had to sign an "STD clause," promising not to sue the network if they catch something. Network insiders, meanwhile, revealed that such provisions are common across all networks, especially on dating shows.
