Following behind the likes of Khloe Kardashian and Taylor Swift from past episodes, this prank really shows just how gullible the Glee gal, 25, can be. 

The actress is asked by a friend to assist in helping her pal’s grandfather while his caretaker is giving medical instructions on the phone, but what she’s asked to do is unconscionable. Little does she know that fellow actress Hayden Panettiere is behind the entire thing!

This isn’t the only celebrity that Hayden punks…

From Zac Efron to Nicole “Snooki” Polizzi, the Heroes star, 22, is getting good at this. The episode airs tonight, April 12, on MTV. Do you have any good pranks? Share them in the comments!
