Audrina Patridge & Corey Bohan: Back Together

Just days after we reported that Audrina Patridge and her ex Corey Bohan were spotted cozying up at a Las Vegas nightclub, we are now hearing that the couple are officially back on again.

The reality star brought her Aussie BMX biker beau to the Hills series finale wrap party Saturday night at the Thompson Hotel in Beverly Hills.

"They are totally back together," a source told us of Patridge, 25, and Bohan, 28. "They were so cute at the party. He had his arm around her and they both looked really happy."

According to our source, the couple, who last broke up in October 2009, never left each others' sides during the bash. "They were sitting alone, whispering in each others' ears and laughing a lot," our source added.

Patridge's rep also confirms the rekindling. "Audrina and Corey have been spending some time together," the rep says. "They are taking it easy and enjoying each other's company."

The Dirty On 'The Hills' Rolling Stone Cover

Back in May '08, Lauren and Heidi had already had a major falling-out and were no longer speaking. So when Rolling Stone called and wanted to put all the stars of "The Hills" on the cover of the mag, the show's producers knew it would take some work to get them in the same room again to join Whitney and Audrina for the scantily clad photo shoot.

"You know, MTV press called us up and they said that Rolling Stone is interested in doing a cover for 'The Hills.' So, of course, you know, it's the best call you can get," show creator Adam DiVello recalled in an outtake from "The Hills: Revealed." "I mean, for me anyway, every cover to me is iconic. I love the magazine, and the thought of a show that I created getting on the cover of Rolling Stone to me was an end all, be all."

The cover came with one big caveat: "All four girls, bottom line, no ifs, ands or buts," DiVello recalled. "When you've got Rolling Stone calling [and] they want your cast on the cover of the magazine, but two of your castmembers don't want to be together in the same room — namely Lauren and Heidi — it seemed like it was never going to happen. I mean, there was a time when we thought, 'This is not going to happen,' because we were not going to get them together."

But it seemed like the magazine-cover gods were shining on them, and the shoot came together. "You get to the bottom of it and figure out how to make it happen," DiVello said. "And luckily, we pulled it off."

VIDEO: Kristin Has Brody Jenner "Voodoo Doll"

After four years and over 100 episodes of tears, breakups, makeups, drama and at least one shocking makeover (Heidi!), The Hills is signing off. The MTV reality hit's finale airs Tuesday at 10 p.m.

"Everybody's kind of coming at peace with their stories that we've been following along," show creator Adam DiVello said recently of the finale. "A few of them definitely found happiness and what they were looking for."

In this exclusive sneak preview of the final episode, Brody Jenner -- hitting golf balls with pals Frankie and Taylor -- looks back on on-again-off-again gal pal Kristin Cavallari.

Watch how Brody reacts when Taylor snipes that wild child Cavallari is sticking pins into a Brody "voodoo doll."

Lauren Conrad: 'The Hills' To Hollywood Mogul

What began as a reality television gig on “Laguna Beach” has turned into a full-fledged multifaceted career, and Lauren Conrad is counting her lucky stars.

The “Hills” babe left her MTV roots to pursue writing bestselling books and designing clothes and it has definitely panned out for her.

Of her first novel “LA Candy,” Conrad explained, "I didn't take anything specifically that happened to me. The only thing that I did was ... it was a way to show not necessarily me, but just the other side of being on a show like ours. For everyone that's done it, I think you see one side and you don't see the other. It's kind of an interesting story to tell."

As for her LC Lauren Conrad clothing brand with Kohl’s, "It's very much a California brand. It's all about incorporating new trends and putting our own twist on it — relaxed cool without trying too hard.”
