Ashlee Simpson-Wentz is so eager to finally give birth that she may induce labor, her sister Jessica Simpson says.

"They're going to have to. It's already developing really quick," Jessica said Monday at a taping of the The Ellen DeGeneres Show.

Ashlee – described by husband Pete Wentz more than two weeks ago as due at any moment – has already tried other ways to begin labor.

"Different foot massages and stuff," Jessica told DeGeneres in the show airing Wednesday. "I don't know. I think she's really just jumping around trying everything right now."
