Since Virgin billionaire and mogul Richard Branson started accepting reservations for commercial space flights on Virgin Galactic, celebrities have been slapping down their cash to snag a ticket -- and the most recent one to do so is Justin Bieber.

(Yes, we hear some of you hoping he won't come back. Calm down.)

Keeping the Biebs company in zero-gravity? His manager Scooter Braun. Tweeted Branson of their $250K-per-seat purchase:

 
Which made Bieber reply:

Justin previously toyed with an idea of doing a concert in space, which NASA seemed to be totally cool with.

Other celebs to have tickets on Virgin Galactic include Russell Brand, Leonardo DiCaprio, Ashton Kutcher, and Kate Winslet -- who was gifted a ticket as a honeymoon gift when she married Branson's nephew.
