Ashlee Simpson-Wentz is about to pop, and big sis Jessica Simpson says she may induce labor.
The "Blonde Ambition" star revealed during a taping of "Ellen," "They're going to have to. It's already developing really quick." Ashlee's due date was at the end of October. Jess also told Ellen her lil' sis has attempted other methods, "Different foot massages and stuff... I don't know. I think she's really just jumping around trying everything right now."
Jessica's interview airs on "The Ellen DeGeneres Show" this Wednesday.
