Janet JacksonIf you're planning on seeing an animated Brad Pitt, Will Ferrell and Tina Fey this weekend in the new 3D flick "Megamind," you're in for a treat (well, besides listening to Brad's smooth voice!) The trailer for Justin Bieber's upcoming concert movie "Never Say Never" will finally be shown in theaters. The film's director Jon M. Chu annouced on his Twitter today, "Never Say Never trailer premieres in front of Megamind starting today and in 3D!!!! Go to a theater and see it on a ginormous screen."

Of course, if you're feeling up for a double feature, Janet Jackson (pictured) is hoping you'll check out her latest movie, "For Colored Girls." Janet posted about her work in the new Tyler Perry project, "I hope u will enjoy For Colored Girls. It has been an amazing project to be a part of. Thank u Tyler, Ntozake Shange n everyone involved!" Meanwhile, Eva Longoria Parker gave a shout-out to another one of the film's stars when she wrote from her page, "Everyone go watch my sister @kerrywashington in For Colored Girls this weekend! Opens today and its amazing!!!"
