HILLS RECAP: Justin Bobby Does Battle For Audrina's Affections

"It's on," Justin says of coming face-to-face with Audrina's new fling

Audrina Patridge's relationship with Justin Bobby may be on the rocks at the moment, but things were hot and heavy this week on the Hills, with Audrina juggling Justin and her new fling, Cory.

With the return of Australian cutie Cory on her radar, Audrina is quick to put Justin Bobby on the back-burner. After all, Cory actually returns her calls! (Which, as Lauren reminds her, is what normal boys do.) After hitting it off at dinner, Audrina brings him as her date to a beach bash in Malibu with the Hills crew - sans Justin Bobby.

Things clearly go well in Malibu for Cory, because he goes home with an invitation to party with the gang in Cabo San Lucas for Brody's upcoming get-together. The only hitch? Justin's coming, too!

While Audrina faces some tough decisions, Heidi is finally ready to make one of her own: It's time to have a heart-to-heart with Holly.

Spencer has clearly had it with Holly shacking up at Chez Speidi - and he doesn't care who knows it. This week, it's his sis Stephanie who hears out his disgust with the Montag family.

Referring to Heidi’s mom as “stalker mom,” Spencer tells Stephanie that he just can’t take the intrusion of her family, especially since Holly has been living with him and Heidi.

Stephanie’s advice? “You can’t tell Holly to move out. Heidi’s gotta be the one. Just talk to Heidi,” she says.

Taking her advice to heart, Spencer tells Heidi what to do (as if he wouldn’t have on his own!)

“I’m not living with your sister anymore," he says, once and for all. "One of us has to move out."

Heidi, predictably, caves in and later tells Holly that it’s time for her to find a place of her own.

“What am I supposed to do, live on the street?” Holly asks, as she reasons that she still hasn’t found an apartment or job and needs more time. Heidi simply ends the discussion by explaining that her living with them is compromising her relationship with Spencer.

Meanwhile, just when it seems Audrina’s love life couldn’t get more confusing, Audrina reveals to Lauren that since she’s been dating Cory, Justin has been calling her a lot more.

He comes over to the house one night when Lo and Lauren aren’t there, and before anyone can say the word “go” he and Audrina are both naked in the pool together. However, it’s not romantic - Justin clearly has an ulterior motive. Through their kisses, he offers a knowing threat.

“In Cabo, it’s on,” he tells her, referring to the fact that Audrina may bring Cory to Cabo. “It’s on!”
