Snooki -- I'm Pregnant ... AGAIN!

Snooki is plumping up again ... but not 'cause she's eating too much -- the "Jersey Shore" store is having another baby!

Snooks is reportedly a few months pregnant but is keeping things under wraps so it doesn't torpedo some lucrative appearances she has lined up -- according to Page Six.

Sources close to the couple told TMZ a similar story this week ... but we got radio silence from her camp.

Great timing ... Snooki just penned a book called "Baby Bumps" about her first pregnancy in 2012.


Aww, I'm excited for her. She's planning a wedding and pregnant at the same time as Jwoww.
