The Situation was back to his normal routine yesterday in New Jersey -- driving around in his Lamborghini, hitting up the car wash, the gym, and a vitamin store.
As TMZ first reported, The Situation checked out of rehab earlier this week after spending a few weeks at Cirque Lodge rehab center in Utah, where he was receiving treatment for substance abuse.
We've been told producers plan on bringing in new cast members for the next season of "Jersey Shore," so they can slowly phase out Sitch and Snooki.
The show is set to begin filming this summer.
