WATCH: Hayden Panettiere Hosts "Punk'd" And Gets Dianna Agron and Zac Efron Good

We have to admit, watching Hayden Panettiere punk Glee's Dianna Agron and actor Zac Efron made us literally LOL.

She gets sweet Dianna Agron in a sick, sick way. And cutie Zac Efron looks like he might cry and/or freak out at any moment... especially when he's getting put in hand-cuffs.

Hayden's hosting an all new episode of "Punk'd" that airs tonight on MTV at 10:00 P.M. ET/PT. You can catch a sneak peak of her dirty deeds below.

To top it off, tonight's "Punk'd" episode also includes a joke on Jersey Shore's Snooki with the help of JWoww.

Now, you know that's going to be hilarious!
