Megan Fox's past came back to haunt her today ... literally.
The sexy star appears on "The Ellen DeGeneres Show," where she talked about working at a smoothie shop before she was famous -- where she had to sometimes dress as a banana on the street to promote the store.
As she was talking, Ellen had someone sneak up behind her dressed as the fruit and scare the heck out of her!
It was pretty hilarious, check it out above.
Megan is only the latest to be scared by the talk show host. Click here to see her scares for Dylan McDermott, Bethenny Frankel and Jennifer Aniston.
