The Darkest Celeb Scandals Exposed

Between vanishing into thin air and volatile tempers to addictions, celebs rocked the scandal boat more than ever before — and best of all, Star readers knew these first! Click through to find out why these stars had the worst year of their lives.

Star exclusively revealed the shocking genesis of the relationship between Scientology's two most famous followers, Tom Cruise and John Travolta. "John literally became obsessed with Tom after seeing him in Risky Business," a source close to Travolta told Star. That obsession eventually led to one of showbiz's most talked-about friendships — and faced rumors questioning their sexual orientations. And it all started, claimed the source, with a week of bonding between the hunks in the woods of Oregon 30 years ago.

Nicole Richie's husband, rocker Joel Madden, was caught spending time with The Bachelorette hottie Kaitlyn Bristowe at an L.A. nightclub earlier this summer. "Kaitlyn was being super flirty, reaching out to touch his arm as they chatted," the insider told Star. "They clearly had a lot of chemistry."

An exclusive Star investigation uncovered another skeleton in the Duggar closet that predated Josh's misconduct by a decade. According to Washington County (Ark.) Chancery Court documents obtained by Star, Jim Bob's sister, Deanna, asked for an order of protection against then boyfriend Terry (now husband), alleging he had threatened her two days earlier at work. Then, the day their daughter (Amy Duggar) was born on Sept. 30, 1986, another disturbing allegation came: "I had just delivered Amy. Terry came into the hospital room and [said] I should kill you and the baby."

Star exclusively obtained court documents obtained on Jon Hamm, who was issued a 1992 summons to return and face a charge of assault in connection with his central role in a brutal hazing incident — he "hooked a claw of a hammer underneath his [the pledge's] genitals and led him by the hammer around the room"— at the school two years earlier.

In an exclusive interview with Star, the birth mother of Rosie O'Donnell's youngest adoptive child claims that the ex-View cohost and her then wife, Michelle Rounds, made false promises to her in order to get her to give up little Dakota in January 2013 — and abruptly cut off contact with her once the adoption process was through. "Rosie made me feel comfortable, showed my older daughter with lavish gifts and showed an interest in my well-being. It made me feel like, for once, someone truly cared and wanted to give me a chance. None of it was true," Jami Weaver, who lives in a motel in Texas, tells Star.

Hollywood insider Hesham "Sham" Ibrahim, who has been a long-time traveler with the same social circles as Brad Pitt and Angelina Jolie, exclusively told Star in May: "I don't want to define Brad's sexuality, but whatever it is, he's into guys." Sham told Star that Brad's bisexuality has been going on for close to 10 years.

In June, Star uncovered, after multiple sources reported that, in January, Kourtney Kardashian's longtime partner and baby daddy, Scott Disick, left an Arizona nightclub with a coterie of women — one of who claims to have spent the night with him. What's worse, the pair allegedly had unprotected sex — and Scott, 32, was terrified he got her pregnant.

Before Lamar Odom's overdose in October, sources exclusively told Star in July that Lamar knew his second chances with estranged wife Khloe Kardashian were officially over. "I really messed up — she doesn't want anything to do with me," Lamar admitted. "We can't work it out, and I feel so stupid. There's no way I'm ever getting her back."

Obtained exclusively by Star, these sad photos show just how deeply disturbed the alcoholic Kim Richards had been prior to her downward spiral last spring, which included an arrest for public intoxication and battery on a police officer. When the Real Housewives of Beverly Hills reality star could no longer afford her $4,000-a-month, 5-bedroom, three-bathroom property in the San Fernando Valley, the troubled former child star ran riot, trashing the place beyond recognition and then abandoning it.

Star uncovered the shocking reason behind Blake Shelton's divorce from Miranda Lambert: she was sleeping with five other men!

Star exclusively learned Cybill Shepherd's son, Cyrus Zacharia Shepherd-Oppenheim, 27, entered a sober living facility in the Los Angeles area, receiving treatment for drug and alcohol addictions.

Star revealed Tom Hanks' drug addict son, Chet Hanks, 24, fell off the radar for a month in August — leaving his family to fear the worst. Both Tom and his wife, Rita Wilson,"agreed that they didn’t want to file an official missing persons report with the police, that it would be better to try and keep the development out of the press,” a source dished to Star.

In March, Mira Pak secretly filed for divorce from husband Terrence Howard while pregnant with their son, Qirin, citing irreconcilable differences. As for what went wrong, sources divulged to Star it was the actor's notoriously volatile temper.

Rosie O'Donnell's year not only included her daughter Chelsea running away, but also Rosie's father died of cancer. To help cope, Star readers first found out the former The View host was leaning on her new love interest, Tatum O'Neal.

It was hoped that Sandra Bullock's divorce from Jesse James would be a wake-up call to the Oscar-winning actress, but unfortunately, Star discovered her new boyfriend, Bryan Randall — an L.A.-based model and photographer — came with a dark history of alcohol, abuse, arrests and wild behavior.

After Lamar Odom was found unconscious at a Nevada brothel, Star discovered Khloe Kardashian's estranged husband met his long-time drug dealer in a parking lot of the South Strip Transfer Terminal before exchanging $12,000 in cash for heavy amount of cocaine. "Lamar seemed like he was already messed up — he was sweaty and mumbling some of his words. At one point, he said 'No one cares if I'm dead or alive,'" a source told Star.

On Dec. 9, a Star insider caught Heidi Klum's boyfriend, Vito Schnabel, at Manhattan's White Horse Tavern, packing on the PDA with actress Dakota Johnson. "They even held hands on and off," dished an eyewitness.
