The Hills

Doug Reinhardt's neighbor is really eating his hat now -- after he took the former "Hills" star to court and demanded a restraining order ... the judge ordered the NEIGHBOR to pay $50,000.

TMZ broke the story ... Reinhardt's real estate agent neighbor obtained a temporary restraining order against the reality star back in December, claiming Reinhardt had threatened to "beat the f***" out of him for complaining about his late night parties.

The neighbor was back in court recently -- to see if the judge would make the restraining order permanent -- but not only did the judge deny the neighbor's request ... he ordered him to pay $49,500 to cover Doug's legal fees.

One thing is undeniable ... Audrina Patridge is pretty ... out of tune when it comes to singing -- but that didn't stop her from rocking a legendary stage in Las Vegas this weekend.

The former "Hills" star went to Rock n' Roll Fantasy Camp at the House of Blues in Vegas and got to perform an original song with actual rockstar, Lita Ford.

It's unclear how many days Audrina spent at the camp -- but she obviously spent more time on her rocker chick moves (decent) than anything else.

Hey, at least she's living her dreams. Off key, but still ...

For the record, AP ... here's how it's done. Classic Lita.

"Dancing" does a body good ... and Audrina Patridge and Cheryl Burke are the proof.

The ladies are both in Hawaii (on separate vacations) ... flaunting their incredible "Dancing with the Stars" physiques on the beach ... and it's NICE!

Still, we gotta ask ...

12:45 P.M. PT -- We just heard from Reinhardt's attorney who told us, "Doug Reinhardt was surprised and very disappointed that one of his neighbors took a complaint about alleged noise at a party that could have been handled in a conversation over the backyard fence to the courts." He says Reinhardt is looking forward to telling his side of the story in court.

Doug Reinhardt -- former Paris Hilton BF who appeared on "The Hills" -- has been hit with a temporary restraining order after allegedly threatening to "beat the f**k" out of his neighbor, TMZ has learned.

The 29-year-old -- who's also the heir to a frozen burrito fortune -- has been living in a $15k-per-month home above the Sunset Strip, according to legal docs ... and his next-door neighbor says he's been a total nightmare.

The main issue ... the neighbor, a bigtime real estate agent, claims Doug's been throwing crazy parties that don't START until 2:30 AM.

And when the neighbor complained, he says Doug called him a "pain in the butt" and said, "I'm going to beat the f**k out of you."

The neighbor says he fears for his life ... and begged the courts for protection.

We've learned ... the judge issued a temporary restraining order against Doug, requiring him to keep his distance from the guy -- a whole 5 yards (since they're neighbors, any other distance would essentially require one of the parties to move).

So long crazy F-cups ... Heidi Montag has unveiled her new C-cups after undergoing yet another breast-related medical procedure in October ... this time to REDUCE her breast size.

You'll recall, Montag famously underwent 10 plastic surgery procedures in one day back in 2010 -- including a mini brow lift, liposuction, buttock augmentation, Botox, a nose job, fat injections in her cheeks, nasolabial folds and lips, chin reduction, and increasing her breast size to F-cups.

Montag says she was young and "unstable" when she got the procedures ... and now warns other girls about making the same mistake.

Audrina Patridge dropped a bombshell about her "Hills" co-star slash fake bestie Lauren Conrad! LC hasn't invited Audrina to her wedding yet ... and that means AP is totally pissed!!

Unless, of course, LC just hasn't sent out invitations yet. Then it's totes cool.

12:18 PM PT -- TMZ spoke with a rep for the Evanston Police Department ... who tells us Kristin was initially stopped for speeding early this morning.

During the stop, the officer learned Kristin has been living in the state and driving without a valid IL license, which is against the law in IL.

Cops say Kristin was required to travel to the police station, in her own car, and was ultimately hit with a citation for $120 ... despite the fact that EVERYONE ON THE PLANET knows she splits her time between L.A. and Chicago because she's married to Bears QB Jay Cutler.

Cops say if Kristin wishes to continue driving in the state, she must get a valid IL driver's license.

Kristin Cavallari says she was taken into police custody in Illinois this morning -- and forced to post bail -- and claims it all has to do with her driver's license.

KC went to Twitter moments ago and said, "Who knew having a California driver's license in Illinois was a CRIME to be escorted to the police station to post bail?!! What a morning."

The former MTV star -- who's married to Chicago Bears QB Jay Cutler -- is insinuating that she had the same problem Justin Bieber had in L.A. ... when he was cited for not having a valid driver's license.

In Illinois, you are required to have an IL driver's license once you have lived in the state for 90 days ... or you can be cited.

However, KC says she's not a full-time IL resident and therefore shouldn't be subjected to that law. She also tweeted about it saying, "I still have an apartment in LA so I'm a resident of California."

Story developing ...

What did Spencer Pratt do for his 30th birthday? He watched his plastic girlfriend Heidi Montag jump out of a plastic cake at a strip club in Vegas. Woooo adulthood.

Spencer, looking a little fuller these days, celebrated the day of his birth inside the VIP section of famous strip club gentleman's club Crazy Horse III on Saturday along with Heidi and friends.

In the pics Heidi goes all Marilyn Monroe on a giant fake cake. Spencer looks pretty happy about it.

This video is pretty great ... Kristin Cavallari messing with the paps after a night of clubbing in Hollywood -- shakin' 'em down for cab fare in exchange for a photo ... and it's awesome.

It's that classic KC bitchiness we all know and love ... with the reality star shaming the paparazzi for $5 outside Hooray Henry's in Hollywood -- "I just posed for you. Pony the f*ck up."

Eventually, one of the snappers opens his wallet ... but Kristin was clearly not impressed.

It's not like she needs the money -- her husband Jay Cutler is at the end of a 5-year $50 million contract.

Proof Jay Cutler actually went through with it -- Kristin Cavallari just posted this happy wedding photo with her new hubby ... nearly TWO YEARS after he torpedoed their first engagement by dumping her ass.

At least this wedding dress turned out better than the last ones ...

Second time's a charm.

Jay Cutler is finally gonna make an honest woman out of his baby mama ... TMZ has learned the Chicago Bears QB just purchased a marriage license in the state of Tennessee.

We've confirmed ... Cutler and Kristin Cavallari appeared at the Davidson County Clerk in Nashville, TN early this morning ... and dropped $99.50 on the paperwork required to tie the knot.

Sources connected to the couple tell us ... the two are set to swap "I dos" at a ceremony THIS WEEKEND in Nashville ... the city where Jay went to college (he played at Vanderbilt).

The marriage license is only valid for 30 days ... so if Jay has a last minute change of heart this weekend, Kristin still has a couple of weeks to change his mind.

Jay and Kristin were originally engaged back in April 2011 ... but called it off in July.

Just a few months later, they announced the engagement was back on ... and in January 2012, they revealed Kristin was preggo with Jay's kid.

Kristin gave birth to their son Camden on August 8, 2012.

So far, no comment from Cutler or Cavallari.

Congrats!!

UPDATE 12:33 PM PT -- Kristin posted a pic to her Instagram of a pair of wedding rings with the caption: "Im officially Kristin Elizabeth Cutler!!!!!"

Lauren Conrad might be old as the "Hills" ... but she's still rich as ever ... plunking down $3.74 million on her new L.A. mansion.

Sources close to the deal tell TMZ, the 27-year-old former MTV star purchased the 4,300 sq. ft. 6-bedroom, 5-bathroom Brentwood home this week.

It's two stories ... with a brand, spanking new kitchen, huge backyard and a basketball court. It was remodeled recently by celeb interior designer Jeff Lewis from Bravo's "Flipping Out."

While most of the country is freezing their asses off, former "The Hills" star Audrina Patridge warmed her sexy bones by slipping into a tiny bikini and hitting the sand with her pup in Manhattan Beach.

The 27-year-old is the perfect cure for the winter blues.

Former "Hills" star Audrina Patridge is selling her bikini-clad body (again) -- stripping down for a smoking hot 2013 swimsuit calendar -- and TMZ has every month's picture.

Trust us, it's awesome. In fact, it has everything you could ever hope for ...

Audrina's boobs ... check.
Audrina's boobs oiled up ... check.
Audrina's boobs by a pool ... check.
Audrina's boobs on a chair ... check.
Audrina squeezing a dog in her boobs ... check.

Former reality trainwreck Heidi Montag took a break from living in obscurity to wash up on the beach with all her augmented fake body parts in a skimpy red bikini in Santa Monica on Wednesday.

The 26-year-old former "The Hills" star -- who infamously had 10 plastic surgery procedures in one single day back in 2009 -- did some of her best acting while hamming it up for the cameras on the sand.
