'Jersey Shore' star Mike 'The Situation' Sorrentino takes the sober road

Mike Sorrentino is serious about staying sober.

The "Jersey Shore" star - who spent time in rehab earlier this year for addiction to prescription painkillers - hit up Hurricane Club this week but kept his partying in check.

According to a witness, the Situation and a "group of lovely lady friends" drank virgin coconut cocktails all night.

"They had a fun and relaxed evening," the witness added.
