Aly Michalka: Watch HELLCATS Tonight!

Aly Michalka keeps her head down as she heads back to her car after running some errands on Monday afternoon (May 16) in Calabasas, Calif.

The finale of the 22-year-old actress’ show, Hellcats, is on TONIGHT!

In “I’m Sick Y’All,” a strep-throat epidemic hits the university and could hurt the Hellcats as they head to Nationals; and Marti (Michalka) and Deidre (AJ Michalka) still have a lot to process after their big discovery.

“I’m Sick Y’All” premieres TONIGHT @ 9PM ET/PT on the CW. Enter our finale contest too!
