The last person in the world who should be going undercover is rapper Post Malone. Still, he tried it anyway at a record store when he pretended to be an employee. His fans spotted him almost immediately, but everyone else was kind of clueless. The prank was part of the plan to promote the new contest from Omaze where you could meet Post Malone AND walk away with a brand new Bentley. So if you'll excuse us, we have a contest to enter.
