HILLS RECAP: Spencer Pushes His Luck to Win Heidi Back in Vegas

PLUS: Lauren tries to salvage her fragmented friendship with Audrina

The Hills third season finale picked up where last week left off: with Heidi in Las Vegas for a new job prospect and homeless and depressed Spencer sulking at her homestead in L.A.

Clued into his girl’s plans to work – perhaps permanently - with boss Brent Bolthouse on a new project in Vegas, Spencer has an a-ha moment and enlists sis Stephanie as his Sin City accomplice. "We're going to Vegas!" he enthuses, clearly on a mission.

Arriving on the Strip, Spencer sneaks up on Heidi as she sips business cocktails at Dos Caminos with her bosses. Embarrassed, Heidi excuses herself from the table and the two duke it out in classic Speidi style. Finally, Spencer puts his cards on the table: "We need to be together – Just come back to L.A. with me."

Without a fight, Heidi succumbs to Spencer's plea, missing her flight home with her bosses to travel with her boyfriend instead. Could things be looking up for these love-to-hate-them lovers?

Back in the Hills, LC desperately attempts toreconnect with Audrina, who decides to make a move to check out other apartments with Justin Bobby in tow. Trouble in paradise? So says Lauren, who is distraught over her faltering friendship with her former bestie. The tipping point? Audrina is a no-show at LC's roommate bonding dinner.

That’s it, Lauren declares, as she makes the long trek to Audrina’s guesthouse, only to find her pal anxious to place blame – on Lo. In a civil-for-the-cameras conversation, Audrina finally admits that she thinks Lo is causing their bond to break. "Everything was fine when it was just me and you living together, and...[with] Lo in the picture, you're distant from me,” Audrina says.

Lauren's response? "Lo has done nothing to push us apart on my side. I never let the opinions of others affect my friendships."

Sometimes, three really is a crowd.
