It's T-Shiiiiiiiiiirt time -- or at least it will be soon -- because Mike "The Situation" Sorrentino is back in front of reality TV cameras.
Sources close to the situation tell TMZ ... the "Jersey Shore" star -- who has alluded to getting his own reality show -- has already started shooting. We're told the show centers around Sitch AND other members of the Sorrentino clan ... living it up in the NJ burbs.
It's unclear if a network is attached yet ... BUT we're told the house Sitch is renting during production is right next door to the place where Snooki and JWoww taped their spin-off.
In case you're wondering what's in store ... we got footage of the GTL guru taping a few scenes ... which involve him getting in and out of his Lamborghini.
