Marilyn Manson to Paris Jackson -- You're ALWAYS Welcome At My Shows

Paris Jackson won't ever have to worry about missing another Marilyn Manson concert -- 'cause the goth rocker tells TMZ she'll get the VIP treatment whenever she wants to come to a show.

We broke the story ... Paris "threw a fit" hours before her suicide attempt when she was told she wasn't allowed to attend an MM show. We're told she ran into her room screaming and slammed the door.

After learning about the incident, Marilyn says he has a message for Paris -- "I hope you feel better. You will be on my guest list anytime you want."

Paris is currently being hospitalized after she took a meat cleaver to her arm and swallowed a bunch of pills early Wednesday morning.
