Mike "The Situation" Sorrentino is in a tough situation.
The "Jersey Shore" star, 30, who entered rehab for substance abuse in March, "isn't sober anymore," a source tells Us Weekly in the new issue, on stands Friday.
Indeed, at West Hollywood's London hotel on Sept. 26, a witness saw him "downing so many cocktails, he could barely stand."
His rep, however, responds, "He has not been drinking."
In his first interview after completing an inpatient treatment program, Sorrentino told MTV News, "Ever since I've been out, I'm not gonna lie ... it's not easy."
The insider adds to Us that the Sitch is stressed the MTV series is ending: "Mike's freaking out about what he's going to do after the show."
The final season of "Jersey Shore" premieres with a double episode on Thursday, Oct. 4 at 10 p.m. EST on MTV.
