With the episode set to air on Wednesday (April 4), the 23-year-old actress visited the daytime talk show as part of her promotions leading up to the July 3rd release of "The Amazing Spider-Man".
Grabbing a seat alongside Miss DeGeneres, Emma appeared to have a case of arachnophobia - as she lunged backwards and offered up quite the perturbed face as Ellen reached her hand in a container holding one of the eight-legged creatures.
During the course of the visit, DeGeneres also put Miss Stone in a tough spot by asking her to name the better smoocher - with the two choices being Mr Garfield and her "Crazy, Stupid, Love" co-star heartthrob Ryan Gosling.
Not falling for the trap, Emma elusively answered, ?Apples and Oranges. Ya know, um?I love all fruit."
