Levi's Going 'Full Johnson' for Playgirl

We've confirmed Levi Johnston plans to come out swinging -- the famous Palin-impaler is gonna go the full monty for Playgirl.

Levi's manager already said he was 90% sure the teen baby daddy would take it all off for the adult rag -- but now comes the confirmation ... in the form of the greatest statement ever:

"Everything's gonna hang out. We're talking full johnson."

His manager tells us Levi's gunning to shoot the nudie pics on November 16th ... the same day Sarah Palin makes her Oprah debut.

A Playgirl rep tells us of the shoot: "We're working on some athletic scene stuff for Levi: gyms, rinks - that sort of thing."
