Watch: Lance Armstrong Threatens to Leave 'Stars on Mars' after Disagreement over Trans Athletes

Lance Armstrong said he was going to "auto-select myself to leave" after disagreeing with others in the realty game show's cast about transgender athletes, Entertainment Weekly reported.

In a teaser for this week's episode, airing July 17, Armstrong, 51, tells 25-year-old Ariel Winter, an alum of the inclusive comedy "Modern Family," "Ariel, let me make this really simple: I don't need the drama."

Declaring that he "busted my ass for nine days, I'm gonna bust my ass on the 10th day, and I'm going to auto-select myself to leave," Armstrong then hashes it out with Porsha Williams, 42, of "Real Housewives of Atlanta" fame, who tells the former cycling champ, "That's not even fair for the team for you to say, 'Oh, I'm gonna opt out.'"

Williams goes on to chastise Armstrong, telling him, "I'm tired of people giving up because it's really making the experience not fun."

Responding to Williams' argument, Armstrong – looking at Winter – announces, "I'm not living in this hab another day with certain people."

The game show, which is narrated by sci-fi legend William Shatner, places celebrities in a mockup of the kind of habitat that astronauts might use on an expedition to the planet Mars – hence the show's "Stars on Mars" title.

Armstrong had clashed with castmates about the issue on a previous episode, demanding of mixed martial arts fighter Rhonda Rousey, 36, "why the creation of a separate category of competition for trans women in sports would be 'unfair,'" the Daily Beast recalled – "an interesting choice of words from the disgraced cyclist who has confessed to using banned substances for the majority of his career," the outlet noted.

The cyclist's query made others on the show "visibly uncomfortable," the Daily Beast noted, with Winter "rolling her eyes before singer Tinashe chimed in, 'I think we just have to care about if you otherize people,'" the article recounted.

Williams "agreed," the Daily Beast continued, "pointing out that they weren't sitting at his kitchen table, where perhaps such candid, if controversial, statements would be appropriate to articulate."

Openly gay figure skater Adam Rippon, also in the cast, commented on the exchange, telling the Daily Beast, "It was just so inappropriate."

"Nobody wanted to have this conversation," Rippon, 33, went on to say. "Especially on this cute little reality show where we all had to live together for weeks on end."

According to Rippon, Armstrong pursued the topic, declaring during dinner the following day that the "problem with America is that nobody wants to have these uncomfortable conversations."

"Armstrong then directly addressed Rippon, asking him why he wouldn't engage," DB relayed.

"I'm not afraid of having difficult conversations," Rippon said in his comments to the news site. "But if we're going to fully open that particular conversation, I want trans athletes [present], I want people who are doing research into this [to be there], and people who are real proponents of seeing women's sports succeed."

"I don't need to hear what the greatest cheater in American history has to say about what he thinks is an unfair advantage."

Will Armstrong follow through and jettison himself from the show? The new episode airs tonight at 8 p.m. on Fox. Watch the preview below.
