'Breaking Bad' Star RJ Mitte — VEGAS RAGER FOR 21ST BDAY … Mom Was There Too

‘Breaking Bad’ Star
… With Mom

0826_rj_mitte_LAUNCH_V2Breaking Bad” star RJ Mitte rang in his 21st birthday by RAGING in Vegas — with tons of hot chicks, tons of hard booze … and his mother???

Mitte — who plays Walter White Jr. on the AMC show — hit up Ghostbar at the Palms Casino Resort this weekend … where he partied hard with his BB co-star Daniel Moncada, “True Blood” actress Lindsey Haun and Amanda Fuller from “Last Man Standing.”

… and his mom was there, too!

But parental supervision didn’t keep Mitte from enjoying all that Vegas had to offer — we’re told the actor downed some Jack Daniel’s Tennessee Honey cocktails while cake fighting with some babes.

Hopefully RJ’s night of boozing ended better than that time WW2 got drunk …
