Three major cast members might not return for another season of "Saturday Night Live".

A source told Us Weekly that Kristen Wiig, Jason Sudeikis and Andy Samberg will reportedly leave the show after this season. "It will be a huge blow to the show," according to the source. "Without Andy's video shorts and Kristen saving every skit, they'll need help!"

Another source said, "Kristen was talking about leaving a while ago. With her movie success, it's no surprise."

But don't panic, though. Reps for Wiig and Sudeikis told TVGuide.com, "There's no truth to that Us Weekly item. Those decisions won't be made until the season is over." And a spokesperson for SNL said, "No decisions have been made and won't be until the end of the summer."

Samberg's rep had yet to comment.
