Yes, this old man really is Channing Tatum

Channing Tatum shows off his old man make-up on Instagram.

Actor Channing Tatum left fans stunned after turning up disguised as a balding, old marketing executive at a pretend screening of the Magic Mike sequel.

The Hollywood hunk teamed up with officials at charity website Omaze.com to launch a competition offering one lucky lady the chance to attend the Los Angeles premiere of Magic Mike XXL with Tatum himself.

He decided to promote the prize by inviting a group of devotees to what was billed as an advanced screening.

He posed as veteran studio employee Scott Galsey for the stunt to ask attendees what they thought of the original 2012 film, and then told them they would be seeing Magic Mike XXL in 3D.

However, instead of screening the new movie, he treated guests to a sexy performance from a group of male strippers.

Tatum, as Galsey, was then invited to join in and dance and he subsequently pulled off his wig and fake beard to reveal his real identity.

The stunt was filmed to promote the contest, which ends later this month, and was posted online today.
