Megan Fox is in negotiations to join Judd Apatow's Knocked Up spin-off starring Paul Rudd and Leslie Mann.  THR reports that Fox's role is currently unknown and no plot has currently been revealed for the film other than Rudd and Mann will reprise their bickering husband-and-wife characters from the 2007 comedy.  The under-wraps film is currently set to be released on June 1, 2012.This is the latest comedy that Fox has signed on to.  She previously boarded Jennifer Westfeldt's ensemble comedy Friends with Kids with Jon Hamm, Adam Scott, and Kristen Wiig.  Fox's latest film, Passion Play, was picked up at the Toronto Film Festival despite abysmal reviews.  Play, which co-stars Mickey Rourke and Bill Murray, will be released directed to DVD.  While Fox hasn't landed a hit in a while, she can be charming when given the right material. Hopefully this new supporting work in these upcoming comedies will help to re-establish her.
