The sexy star teamed up with Omaze in honor of the annual (RED) Shopathon to support of World AIDS Day 2016 to give one lucky fan a trip to Las Vegas with Tatum to catch Magic Mike Live.
The winner will get a free stay at the Hard Rock Hotel and the chance to not only see Magic Mike Live with Channing but also compare abs with the "Magic Mike" star.
Though there's still time to enter, the "Step Up" star gave a few unsuspecting office workers a sneak peek of what they can expect in Sin City with him if they win the trip -- check out the video above to see Tatum's hilarious Elvis Presley impression!
In the clip, the 36-year-old greets workers from the elevator in a head-to-toe Elvis costume. From his hilarious dance moves to his singing skills, Tatum has a pretty spot-on Elvis impression.
He then surprises them with a casino set up on the top floor ... where his show's dancers start stripping.
Most shocking: none of the elevator riders knew Channing was sharing space with them until after he took off his wig. Check out the reveal above!
