'Jersey Shore' Phasing Out Snooki, The Situation: REPORT

Can you imagine a "Jersey Shore" without Nicole "Snooki" Polizzi or Mike "The Situation" Sorrentino? Well, you better get used to it. According to TMZ, sources are saying that 495 Productions is looking to cast new house members to replace the show's biggest breakout stars.

Although 495 had no official comment, show insiders are reportedly concerned that due to Snooki's pregnancy and The Situation's current rehab stint, the MTV staple will "lose its sex-crazed alcohol-fueled edge."

Snooki confirmed her pregnancy on the cover of Us Weekly magazine in early March, though she knew she was expecting since January.

The Situation landed himself on 495's ditch list when he entered rehab several weeks ago to battle substance abuse issues.

"I want to set the record straigh," Sorrentino told website SitchNews.com. "I have voluntarily taken steps to get control of a prescription medication problem I had due to exhaustion. I have spent the past several weeks getting treatment for this problem and recuperating from my work and appearance schedule. I appreciate my fans support and love you guys."

Although the entire cast -- including Situation and Snooki -- will appear on Season 6 of the hit series, TMZ reports that the pair will receive less screen-time than their housemates in attempts to phase them out of the show. MTV announced Monday that the sixth season will begin filming this summer.
