We caught a VERY pregnant Ashlee Simpson outside the Beverly Hills Medical Plaza Monday afternoon.

Now, big sis Jessica says Ashlee is apparently so ready to welcome her little bundle of joy, she may induce labor.

People Magazine reports Jessica made the remarks during a taping of The Ellen DeGeneres Show on Monday.

Two weeks ago, Ashlee's hubby Pete Wentz said the baby was due "any moment now" and now that the baby still hasn't arrived, Jessica says the pair are trying a number of unconventional 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."
