Snooki Moves Into Safe House ... Right Next Door!!!

Snooki isn't taking any chances filming "Jersey Shore" this season with her unborn child -- moving into a shack of her own yesterday ... RIGHT NEXT DOOR to her old stomping grounds.

TMZ broke the story ... the mama-to-be is taking her pregnancy extremely seriously, choosing to live next to the "Shore" house rather than in it because of her loud, boozy ex-roommates.

But Snooki isn't moving far -- in fact, her old digs are mere feet away from her new parenting pad ... a cozy single-family home directly adjacent to the "Shore" house that rents for about $2,000 a month.

Snooki announced she was knocked up in February, and could pop while they shoot Season 6 -- so she wants to be prepared.

As for other big changes this season -- Situation's sober!!! Get ready for an exciting summer.
