Sex Tape Rumors

Word spreads that Conrad made a sex tape with ex-boyfriend, Jason Wahler, but they both adamantly deny the rumors. And Conrad soon predicts that ex-BFF Heidi Montag, whom she started feuding with after Montag began dating instigating bad boy Spencer Pratt (right, with Montag) during the second season of The Hills, started the sex tape rumor with Pratt. Pratt posts vulgar comments about Conrad on his Web site: "It's sad that she destroyed the sex tape...[It] would have made her real famous."

A Feuding Third Season

"You know what you did!" Conrad repeatedly screams at Montag during a confrontation at L.A. hotspot Les Deux in the third season premiere of The Hills. Conrad calls Montag "sad," while Conrad's new roommate Audrina Patridge calls Montag "brainwashed" by her manager-fiancé Pratt, who has been bad-mouthing Conrad in the press. Although many question the show's authenticity, the Conrad-Montag-Pratt feud helps drive ratings, drawing in 3.7 million viewers and making the premiere the highest rated show for MTV this year.

Lauren & Heidi Reunite on Rolling Stone

Conrad, 22, and Montag, 21, appear together – with Audrina Patridge, 22, and Whitney Port, 23 – on the cover of Rolling Stone. The shoot is the first time the two frenemies have been photographed together since their ratings-boosting feud. The magazine calls The Hills "a maddeningly addictive TV show in which nothing ever really happens." Show villain Spencer Pratt says, "If Lauren and Heidi were friends, people wouldn't tune in."

MTV Shoots, Conrad Scores

Conrad appears on the cover of Entertainment Weekly, where she talks about living her life on camera. "Sometimes I wake up in the middle of the night and think I'm being filmed," Conrad says of allowing MTV cameras into her life for The Hills – which premieres its fourth season on August 18. "Every season, I think it's the last. Right now, I think this is the last season."

Lauren Keeps Mum on Kyle

Conrad is spotted awfully close to 30-year-old actor Kyle Howard at the Malibu shore, but plays coy when asked if she and the My Boys actor are an item. "I'm just dating," Conrad, 22, tells PEOPLE.

Feuding Over Justin Bobby

A rumor about Conrad and Justin Bobby hooking up causes Conrad and Patridge to publicly lash out at one another. "You KNOW I didn’t do this and I have never given you a reason not to trust me," Conrad writes on her MySpace page, directly addressing Patridge, who eventually apologizes to Conrad on camera for assuming the worst.

Leaving The Hills Behind

Conrad bids adieu to The Hills after five seasons, and expresses her frustration with the show's producers in the July issue of Cosmopolitan. "What they didn't get is that I didn't want to fight with her anymore," she says of the staged reconciliation between her and Montag. "I'm trying to move on, but they won't let me." She also releases her debut novel, L.A. Candy, which tops the best sellers list.
