Heidi, 32, rocked denim on denim with her fur-trimmed jean jacket and matching ripped bottoms. She also sported hot pink sneakers, a pink tank top and fuchsia pocketbook.
Audrina, 34, opted to wear a rock star-inspired black leather motorcycle jacket and a dark burgundy maxi dress.
Heidi held on tightly to a box full of her things as she focused on her phone.
The pair was in full on hair and makeup to help look their best for filming.
The Hills revival will reunite many of the old cast members like Brody Jenner, Frankie Delgado, Jason Wahler, Justin "Bobby" Brescia, Stephanie Pratt and Whitney Port. Newcomers Brandon Thomas Lee and Mischa Barton join the original cast members.
The Hills: New Beginnings premieres June 24 on MTV. The first trailer for the new series was released last month and proves that things in the hills are still unwritten.
