He uploaded the pic, with a huge grin on his face, captioned, "Shizzzz happens.... sorry @ginabina77" (which is his Mum's Instagram account).
He later shared the final result on his Instagram story, where you can see he got the word "MagCon" tattooed under his eyeball!
"I LOST A BET LOL," he added.
Look, as beautiful as Cameron is and how cool tattoos are, we really don't think he would do something like this for real, and his rumoured BAE Hailey Baldwin was just as suspicious.
Commenting on his Instagram pic, she wrote, "U would literally never in ur life. Stop trying to finesse the gram @camerondallas," adding a sassy eye rolling emoji.
So is it real?! OF COURSE NOT!
Cameron took to his Twitter last night to clear the air, writing, "Pranks on pranks on pranks."
So cheeky. But one thing he really isn't lying about are the pranks, because the face tattoo wasn't his first! Just days before the tattoo reveal, Cam tricked all his fans again, making them believe that he shaved his entire head!
He posted the real looking video on his Instagram, captioned, "MY HAIR IS GONE."
How dare he do this to us. Unfortunately, it seems like there will be more to come, after Cameron revealed the source of all these pranks: a spin wheel!
The wheel has a list of insane dares captioned "Coming soon", with some including: 'pierce belly,' and 'wax chest,' so expect to see some more crazy behaviour on his end.
