Heidi Montag expressed concern for husband Spencer Pratt’s new cowboy hat in the trailer for the new “Hills” episodes. He’s been seen all over Los Angeles rocking the hat, and he seems pretty comfortable in the Western gear — but his friends don’t quite get it.

Kristin Cavallari just sort of laughed the fashion statement off in her devil-may-care style. And former bro Brody Jenner can’t quite figure out what Spencer is up to now that he’s in his wild, wild West phase of life.

“Every time I go to film or I’m filming with somebody else, I hear stories that Spencer’s wearing cowboy hats all the time now and wearing charms, some kind of necklaces,” he told MTV News. “I’ve heard a lot of things, but I haven’t been able to see it myself.”

Little sister Stephanie Pratt thinks the whole cowboy look is just odd. “It’s really fun to make fun of him lately. … I go over to their house, and I’m like, ‘Spencer, stop going through Heidi’s clothes.’ It’s really fun,” she said. “He says the cowboy hat is, like, a gift from Dad and blah blah blah, but he’s, like, getting really scary.”

It seems Spencer is the only one who doesn’t see what the big deal is. “Well, it was because my new father-in-law gave it to me, and he gave it to me with such a serious speech connected to it [about] how much it truly meant to him and his life and everything,” Pratt explained. “For me, it wasn’t really more a fashion statement — it was more something for my father-in-law.”

Lauren Conrad was feeling the love with boyfriend Kyle Howard at new West Hollywood nightspot MI-6, where the couple was spotted making out and flirting on the dancefloor. But when the former Hills star ended up seated near her old nemesis – Kristin Cavallari – there might as well have been tumbleweeds blowing between the two women. The frenemies shot glares back and forth as Conrad texted on her phone and whispered with pal Lo Bosworth, who had Frankie Delgado for backup.

Cavallari, meanwhile, was sitting with her new businessman boyfriend and friends – and the new Hills star bounced back and forth, chatting with everyone except her castmates. And while Cavallari wasn’t too affectionate with Smith, at one point she did put her arms around him.

Though her days of battling Kristen Cavallari and Speidi in the realm of reality TV are officially behind her, no way is Lauren Conrad headed for the unemployment line.

But she doesn’t expect to run up the aisle to collect an Oscar, either.

The former “The Hills” star, best-selling author, fashion designer and spokesperson spent her week launching a second clothing line and finalizing a deal to convert her semi-autobiographical novel “L.A. Candy” into a feature film.

“I think my acting is offensive!” Conrad, 23, told PEOPLE in response to a question of whether she’d consider playing the movie version of Jane Roberts, the heroine of her novel.

“I’m an awful actor, I’m not super comfortable with it. In fact I was just trying to do lines … and they’ll tell you, I cannot memorize lines.”

The Hills are alive with the sound of Kristin Cavallari, the 23 year old newcomer to the Los Angeles based reality show with a special knack for stirring drama and holding a grudge. And while the buxom blonde certainly delivers on her reputation as ‘the mega bitch’ in the new season of The Hills, a great debate was born last night; Is K-Cav more entertaining than LC?

Totally!

The Hills rose to fame with star and narrator Lauren Conrad documenting her life outside of the Laguna Beach bubble she inhabited during high school, leaving behind a life of Steven Colletti, beach parties, love triangles, bad grades, inevitably bitchy trips to Cabo San Lucas and what she then believed, her rival Kristin Cavallari.

But cut to late 2008 in Los Angeles, the new season of The Hills coming to fruition in the minds of Adam DiVello and associates, and you have Lauren Conrad going public with her plans to leave the hit series to pursue a normal, paparazzi free life and clothing line; news hot on the heels of the arrival of Kristin Cavallari, uber bitch and boyfriend stealer, who then goes on to replace LC and spearhead the show as lead cast member and narrator! Wait, Audrina the failed actress/ stage five clinger and Lo weren’t bumped up to narrator? ‘Fraid not!

Despite their lengthy runs on the show, neither Audrina Patridge nor Lo Bosworth was given narrator duties for The Hills. The honor, however, was bestowed upon Kristin, as well as first billing in the opening title sequence. Ouch.

And people love the uber bitch, a fresh new bite on the almost over-done series.

In an interview with night show host, Chelsea Handler of Chelsea Lately, Handler praised Kristin’s raw honesty, confidence and her ability to admit that, ‘yeah, The Hills is fake,’ while maintaining elsewhere that the directors do reply on casting people who “bring the drama”, something this Laguna Beach alum does quite well.

Making a ‘total bee line’ for Audrina’s ex, Justin Bobby, in the first episode of season 6, (who, P.S. Didn’t even say hi to Audrina, god, can you, like, believe that?) Kristin rubbed every single female cast member the wrong way, with the only Hills starlet not to take a post-party stab at the newcomer being Heidi, member of the American marital mess known as Speidi with husband and pratt, Spencer Pratt.

The remainder of the episode centred around Stephanie, Lo, Jayde and Audrina consistently talking about Kristin, what Kristin does, what Kristin is like, should Jayde be worried about Brody now that Kristin is here, does Brody still like Kristin, how Kristin likes Justin Bobby, how Justin Bobby seems to like Kristin, what Kristin and Justin Bobby might be doing, how Justin Bobby and Kristin probably went home together after Frankie’s birthday lunch, how big Kristin’s ego is, how Kristin is a boyfriend stealer… Kristin, Kristin, Kristin!

But for Cavallari, it’s all a job.

The reality star and actress happily admits she was brought on board to purposely shake things up, to do the one thing she knows the directors will love; bring the drama. And at exactly 6 minutes 55 seconds deep into the first episode, Kristin Cavallari is a job well done.
