Think the mean girls in your school are cruel? Wait until you see what happens in Sorority Wars, an all-new TV movie premiering tonight on Lifetime at 9 p.m. ET/PT.

Privileged's Lucy Hale stars as Katie Parker who heads to college and pledges Kappa -- the rival sorority to the Deltas, the one that her mom founded. When the Deltas seek revenge, it leads to an all-out war between the sororities until Katie learns to stand up for herself.

And for some bonus eye candy, American Mall's Rob Mayes also stars in the TV flick!
