Kristin Cavallari -- Stripped Down on Camera

Looking hotter than a toasted sandwich from Subway, Kristin Cavallari threw on her skimpiest lingerie and got downright dirty for an impromptu photo shoot last week.

One of the lucky bastards posing with Kristin is celeb photog Tyler Shields ... who took the pics "just for fun" ... no specific reason.

As for compensation, we're guessing a six-inch turkey on wheat probably did the trick.

K. Cavallari Subway Run During Mom's DUI Bust

TMZ has learned Kristin Cavallari's mother was arrested for an alleged DUI near Chicago, and Kristin was right there in the front seat during the bust, with one thing on her mind ... fast food.

Police in Barrington, Illinois confirm Kristin's mom -- Judith Spies (that's her mug shot above) -- was pulled over at a DUI checkpoint at 2:15 AM late last month. Law enforcement sources tell us Kristin was riding shotgun at the time, and apparently she was a pretty hungry passenger.

We're told Kristin insisted on fleeing to a nearby Subway and yelled at cops to get her water while Mom went through field sobriety testing with officers. As one source put it, "Subway might be open in 'The Hills' but not here in Barrington at 2 AM."

Judith was arrested for DUI. Police say her car was impounded since Kristin admitted being drunk and couldn't drive.

We're told Kristin did not play the "do you know who I am?" card ... impressive since she's rumored to be dating Chicago Bears QB Jay Cutler -- and we know how much Chicago loves Da Bears.

Kristen's rep had no comment.

Spencer Hocking Sex Tape Starring Heidi Montag

TMZ has learned Spencer Pratt is currently shopping what he claims is a sex tape featuring himself and his soon-to-be ex-wife Heidi Montag.

We're told Spencer has contacted the Rolls-Royce of porn -- Vivid Entertainment -- and is asking for a meeting.

As we first reported, Heidi has threatened to sue Spencer over a tell-all book -- but she has not made any mention of a sex tape. Unclear if the alleged sex tape with Heidi is pre or post-op.

Vivid honcho Steven Hirsch tells us, "I just got off the phone with Spencer Pratt about a sex tape with Heidi Montag."

He continues, "We are in early negotiations to possibly come to terms for a deal."

Spencer has told a friend that the alleged tape "makes Kim Kardashian look like an amateur."

Audrina's Alleged Stalker -- Check Your Head

The 25-year-old man accused of stalking Audrina Patridge has pled no contest to the charge today in L.A. County Superior Court -- but before he is sentenced, the judge wants him to get his head checked.

Zachary Loring -- who was arrested outside of Audrina's Los Angeles home back in February -- will now undergo a 90-day psychiatric evaluation to determine whether he should spend time in prison or a mental institution.

Loring is due back in court on September 20 for sentencing -- he faces up to two years in prison if found competent.

Heidi and Spencer Divorce -- The Real Deal

Knock us over with a feather. TMZ has learned ... Heidi Montag is so serious about ending her marriage to Spencer Pratt, she's already lawyered up and she has a game plan.

We've learned Heidi has picked Jodeane Farrell to handle her divorce and this lawyer isn't playing games ... she's already taking steps to get the quickest divorce possible in California.

Farrell -- who has practiced as a family law specialist for 24 years and currently handles divorce mediations -- will be setting up a meeting with Heidi and Spencer in approximately two weeks. We're told both Heidi and Spencer want the divorce mediated -- meaning the two will try and hash out a property settlement privately, wait the six months required by California law, and end their marriage.

Heidi wants Farrell to be the mediator, provided Spencer is down with it. Farrell has close family ties with the Montag family, but she tells TMZ she doesn't think there will be a problem in mediating the deal.

Farrell plans to meet with Heidi and Spencer together, and if he's on board she'll schedule a meeting with their accountant to go over assets and liabilities.

And Farrell says ... so far things are "very amicable" between Heidi and Spencer.

Whether her breakup from Spencer is real or fake -- this five-bedroom house is one helluva place for Heidi to rest her plastic assets while it all plays out.
