HILLS RECAP: Lauren Conrad, Stephen Colletti Go on Date

PLUS: She moves into her new Hollywood pad with Audrina & Lo

Ah, communal living.

New roommates Lauren, Lo, and Audrina are thrilled to move into their new Hollywood digs.

First on the agenda? Throwing a housewarming party!

As they drum up a guest list, Lauren reveals that her high school sweetheart, Stephen Colletti, is in town and plans to attend.

Anxious for the two to get back together, Lo says, "You guys are hanging out again? That melts my little black heart!"

When Audrina mentions that her on-again beau Justin Bobby plans to attend, the room falls silent. "Maybe he will wear his cowboy hat," Lo cracks. Audrina looks visibly uncomfortable.

Fast-forward to the party.

Lauren's face grows sour when ex-fling Brody shows up ... with his new girlfriend Cora. (Lo cracks a joke about how big Cora's boobs look.) Lauren perks up when Stephen arrives and asks her out on a dinner date.

Showing off a new shorter 'do, Justin Bobby also arrives. He and Audrina sneak off to her room to avoid any disapproving looks form Lauren and Lo.

Noticeably absent from the soiree? Stephanie Pratt. She was planning to go, but when she tells Heidi about it, Heidi calls her disloyal. So she stays in with her and watches movies instead.

Later, Lauren and Stephen go on that dinner date. Lauren is unsure if there is still romance between them or if they're just friends.

Stephen makes it clear midway through dinner when he calls their relationship "platonic.”

Slightly disappointed, Lauren returns home and laments to Lo over ice cream. Then, she comes to a realization: Dating Stephen reminds her of being in high school, but she is at a more mature place in her life now.

Tell Us: Should Lauren and Stephen date again?
