Aly & AJ Michalka Jam on 'Hellcats'

AJ Michalka strums a little tune in this new still from Hellcats.

In the upcoming episode “Warped Sister,” As Marti (Aly Michalka) delves further into her family secrets with the help of Julian (Gale Harold), her bond with a mysterious record store employee, Deidre (AJ), grows stronger.

Meanwhile, Savannah (Ashley Tisdale) and Nasty Kathy (Magda Apanowicz) clash over planning Charlotte’s (Emma Lahana) baby shower, and Savannah finds herself in a bit of trouble at school, giving her no other option but to ask her parents for help.

Aly and AJ will be performing a guitar duet of “My Refrigerator Broke,” another exclusive original by Dan Bern, and Bob Dylan‘s “Mississippi.”

Aly is also pictured at the PIX Morning Studios in NYC on Tuesday morning (April 26).

“Warped Sister” premieres Tuesday, May 3 @ 9PM ET/PT on the CW.
