Aimee Teegarden takes a sip of her Activate Water bottle as she attends the Alice + Olivia by Stacey Bendet Shoe Launch Party held at Palihouse Holloway on Wednesday night (August 10) in West Hollywood, Calif.

The 21-year-old actress wore the “Helena One Sleeve Ruffle Top” and the “Black Eric Pant” from the brand and was joined by Aly Michalka at the party.

Aly Michalka and her younger sister AJ enjoy some sister bonding time on Saturday (December 4) in Vancouver, British Columbia, Canada.

The siblings spent time shopping at a luggage store and left with a flower-printed rolling suitcase.

Earlier this week, it was announced that AJ landed a recurring role on Aly‘s CW series Hellcats.

She’ll make her debut in the second half of the season as a girl who works at a record store near Lancer University. More Here! »

Check out this new behind-the-scenes pics with stars Aly Michalka and Ashley Tisdale from their new series, Hellcats.

Aly, 21, told our friends over at TVGuide about the show, “It’s not about cheerleaders looking sexy and shaking pom-poms all the time. It’s about the competitive aspect, how dangerous it is and the fact that these girls are counting on each other to bring it when they’re out there on the field.”

Hellcats, also starring Robbie Jones, Heather Hemmens and Matt Barr, premieres TONIGHT @ 9PM ET/PT on the CW.

Hellcats costars Ashley Tisdale and Matt Barr wait for their lunch as they film a date scene for their upcoming CW series in Vancouver on Friday afternoon (August 13).

The duo were also seen earlier in the month filming a late night scene with costars Aly Michalka, Jeremy Wong and Robbie Jones.

Ashley told Zap2It about the relationship between Savannah and Dan, “She’s used to dates being set up by the church, so she hasn’t had much of an experience with romance. She and [Dan] start to go out, and it creates a whole new triangle in the show. She’s complicated. In some scenes, I want to really go there with emotions and get emotional, but she’s really closed off, so I have to stop myself. It’s hard to keep everything inside, but she’s that character. She’s not open to everybody. She doesn’t let anyone in.”

Hellcats premieres Wednesday, September 8th @ 9PM ET/PT on the CW.
