After all the holiday debauchery of Christmas and New Years, it'll be a relief to see someone else's dysfunctional family squabble enough to kill one another. Enter the Gallaghers, for an all-new season of 'Shameless' beginning Sunday, January 13! Before the big premiere, go behind the scenes of one of Showtime's most scandalous hits as they preview all the schemes, scams and scoundrels to come from another year in the Gallagher household. Get 'Shameless' with a new preview inside!

A drunk father smuggling himself back from Mexico, a genius-level degenerate with a mind-for mayhem, and as much dirt as one can possibly throw on Emmy Rossum can mean only one thing: the new season of 'Shameless' is nearly upon us! Showtime has issued a new behind-the-scenes featurette of our favorite pay-cable dysfunctional family, previewing all the depraved antics TV's most shameless family will find themselves in this year when the show returns on January 13.

The new season follows the Gallagher household some months after the season 2 finale, where Fiona (Emmy Rossum) is further along toward getting her G.E.D. and somewhat bored in her relationship with Jimmy (Justin Chatwin). Frank (William H. Macy) on the other hand finds himself with a new business venture in Mexico, but that’s far from the only scheme the family has cooked up. The new episodes will also boast appearances from former ‘The West Wing’ star Bradley Whitford.
