Mase -- Y'Know Ain't Nothing Changed ... But My Nails

EXCLUSIVE

Mase might not be the same old pimp, but he still needs pimp-styled pampering -- the rapper did a father-son outing to a nail salon. 

Mani-pedi sources tell us Mase and his kid (not pictured) hit up "Lovely Nails" Thursday night in Newport Beach, CA -- and had the staff working three deep to give them the works on their hands and feet.

We're told most of the staff didn't recognize the ex-Bad Boy rapper at first, but they were impressed once he dropped his creds.

Can't nobody hold Mase down ... unless they're trimming his cuticles.
