Modern Family actress Ariel Winter genuinely believed that disgraced Tour de France champion Lance Armstrong was a “real astronaut” during the first episode of the new US series Stars on Mars.

During a producer interview, Winter revealed that she was shocked to see Lance take part in the reality show.

“Lance Armstrong is a real fricking astronaut. He is a real astronaut. He is Lance Armstrong. You need to Google him. You need to know everything about him because he is so cool,” she said.

We’re not sure who else aside from Ariel Winter needs to hear this, but it was Neil Armstrong who was the first person to walk on the moon back in 1969, and Lance Armstrong was an Olympic cyclist who got caught illegally doping over a decade ago.

Winter was so shocked by Armstrong’s inclusion in the show, which sees celebrities enter a 24 days Mars simulation, that she pointed it out to another contestant, and the faux par made its way back to Armstrong.

“If I were Neil Armstrong, I’d be dead,” he said matter-of-factly.

What is Stars on Mars about?

The brand new reality show sees a bunch of celebs “survive” in a 24-day Mars simulation and complete challenges and evictions until one “celebronant” is crowned the winner.

Funnily enough, the series was filmed in Coober Pedy, South Australia because it closely resembles the Mars-like landscape.
