The Hills

Heidi's hills nearly spilled out of her pink floral bikini as she frolicked in the chilly surf with boyfriend Spencer Pratt ... who later went mountain climbing.

Yodel-ay-ee-oooo!

In the new issue of Us Weekly, Montag also says that the reason she never called LC after news broke of the sex tape, which may or may not exist, was because Heidi was in the hospital recovering from her nose and boob jobs! Priorities, people! When asked if the sex tape, which may or may not exist, does in fact exist, Montag said, "No comment."

As far as her relationship with boyfriend/"Hills" resident slimeball Spencer Pratt is concerned, Heidi says, "It's perfect. We have so much fun. I never knew I could love someone like this." While Pratt chimes in saying, "I have never been so madly in love as I am with Heidi. She has the world's greatest boyfriend."

There's no question these two were made for each other.

Lauren Conrad has named a former friend as a culprit in spreading rumors of a sex tape featuring the "Hills" star and her ex, multi-arrestee Jason Wahler. The annoyed LC denies the existence of the tape.

In an interview with Us magazine, sources close to LC say she's "pointing the finger" at former friend Heidi Montag and BF Spencer Pratt, because Montag was the "one person who didn't reach out" after news of the tape broke. Watch your back in them thar Hills!

Montag and Pratt denied any wrongdoing ... and so far, no sex tape has surfaced.

Lauren Conrad is denying she made a sex tape with one of her co-stars, but sources are telling TMZ a different tale.

A rep for SugarDVD.com tells TMZ that they were approached by a third party claiming to have the tape -- allegedly featuring Conrad with her "Laguna Beach" and "The Hills" co-star Jason Wahler. The rep says the company offered $500,000 for the latest star skin flick -- sight unseen. SugarDVD.com reportedly called Wahler's manager and made him the same offer. According to the SugarDVD source, Wahler's manager would neither confirm nor deny the that there was a tape. News of the tape's possible existence was first reported by Perez Hilton.

Mike Esterman, who reps several "Laguna Beach" stars, confirmed to TMZ that he was contacted, but passed the offer on to Wahler's camp.

A rep from Vivid Entertainment, the company that just released the Kim Kardashian sex tape, tells TMZ his company has not been contacted, but would certainly consider making an offer.

Conrad fired back today with a blog on her website that reads, "Jason and I would like to make it clear that we did not make a tape with us having sex. Jason and I are both shocked and hurt that people would say such horrible things about us. I can't believe that somebody would go to such great lengths to try to damage my reputation."

Walking somberly, her head down and clutching some non-Cash Warren arm candy, the "Fantastic Four" star flashed no smile to the flashing paparazzi, one of whom tried to elicit a smile by talking to her in a Mickey Mouse voice. Nice try, but no dice.

Also at Winston's last night was a grotesquely dressed Lindsay Lohan -- who got out the back door, sparing people in front from having to see her getup.

Jump to NYC, where "Fresh Prince of Bel-Air" star Alfonso Ribeiro found himself watching some very energetic fans do the "Carlton Dance" on the streets outside Butter. The club was also peopled by Jay-Z, Quentin Tarantino, sexy Victoria's Secret model Alessandra Ambrosio, and the girls from "The Hills" -- LC, Whitney & Audrina -- who partied with fellow MTV reality show star Ashley Parker Angel.

Music producer "J.R." Rotem (recently dropped by Britney) had mad love for TMZ calling the site the "classiest" of them all. Could be because we're the only ones who care!

Brody Jenner and Kim Kardashian flashed their pearly whites, followed by Brandon "Greasy Bear" Davis and all his oily glory. While NBA star Dennis Rodman seemed a bit overwhelmed by the lights/camera action, Jesse McCartney and Jack Osbourne were unfazed by the attention.

See all of last night's chilly action in today's Star Catcher.

Brody Jenner's apparently got a thing for the girls of reality TV -- specifically blondes from "Laguna Beach."

The "Prince of Malibu" was spotted heading into Shag last night with none other than Lauren Conrad, the well-known arch-enemy of his ex-girlfriend Kristin Cavallari. While TMZ could not confirm any romantic connection between the two, hanging out with your ex's enemy in public is still a pretty bold move. Also along for the evening was LC's "The Hills" co-star Heidi Montag.
