Paris Jackson Invisible Ink ... No Tats for Photo Shoot

Paris Jackson didn't quite look like herself as she took a smoke break Tuesday -- turns out ... it's because she's hiding something.

Michael Jackson's daughter was spotted Tuesday stepping out of her hair and makeup trailer for a photo shoot in L.A., and it looks like she got a lot of extra makeup ... on her arms to cover up her tattoos.

As you can see, Paris usually flaunts her ink with pride, but for whatever reason ... tats were a no-go for this shoot. Looks like her chest art got the cover-up treatment, as well.

Despite going with a more classic look than she's used to, Jackson looked amazing in an off-the-shoulder red dress ... and still managed to show off some leg.
