When a strange, balloon-shaped flying object zipped across the Californian sky this week, it left millions of onlookers confused and nervous about what it might have been.
It wasn't long, though, before Tesla CEO and space-travel entrepreneur Elon Musk assured everyone that it was merely a test rocket for his SpaceX intergalactic travel enterprise.
Elon let concerned citizens know he'd launched the rocket from the Vandenberg Air Force Base in California.
The Falcon 9 booster rocket had 10 satellites on board, for distribution across the globe.
Regardless, a number of celebrities were unconvinced.
Demi Lovato was first to sound the call for truth.
Zendaya was just as sceptical of Elon's explanation.
Rapper will.i.am was straight-up stumped.
As was Don Cheadle.
And Orlando Bloom was as excited as a kid on Christmas morning, regardless of whether it was a SpaceX test run or a UFO.
