Chrisean Rock's New Blueface Ink 100% Real, Says Tattoo Shop

Chrisean Rock showed off some fresh ink last week that bared the mug of her on-and-off boyfriend, Blueface, and while some thought it wasn't real ... we're being told otherwise.

The owner of the Lakimii Tattoo Shop in WeHo -- where Chrisean got this job done -- tells us the reality star came by for this new face tat last Saturday ... and while they normally have a policy against needling up someone's face, they made an exception for Chrisean.

We're told this work took about 4 hours in total to complete ... which is evident in how detailed and elaborate it is. No word on whether they charged her or not -- but the owner, Timo, tells us they've done tats for her in the past ... so they're familiar with her as a client.

Anyway ... you can take a look at the tattoo in more detail here. While there've been some who've believed this may have been a henna thing ... Timo insists it's the real McCoy.

It certainly looks like it could be based on what we're seeing -- you can see her pores opened up, and the ink filling them. Plus, her head is slightly shaved around the area in question -- which is a telltale sign that a tattoo is about to take place.

There's a handful of folks who are still skeptical about whether this is fake -- but from the looks of it, Chrisean appears to have gotten blasted again ... this after re-devoting herself to Blueface, who's currently behind bars on a probation violation in L.A.

She certainly seems happy waiting for him to be released ... and we know Lakimii is also stoked. They tell us business has booming for them ever since the ink job they did for her.

And get this ... we're told Blue himself apparently has plans to come and get some fresh ink as well. No word on when exactly that might happen -- he could be locked up for a while.
