Christine Applegate, Dax Shepard and More Stars Willingly Spilling Their Own Shocking Secrets

Celebrities are spilling their own secrets this week — some to get positive press, others to get weight off their chest — and the Enquirer has rounded up the most shocking revelations.

Benny and Selena’s Bipolar Battle

Newlyweds Selena Gomez and Benny Blanco have different challenges to tackle than other couples — namely, her bipolar disorder. The pair, who tied the knot in September, just opened up about managing the “Hands to Myself” singer’s mental illness together. “She’s having mania and she doesn’t know,” the record producer, 38, shared in an episode of his new podcast Friends Keep Secrets. “It’s such a delicate thing ’cause you’re not supposed to technically talk to the person, really, about it while they’re deep in it.” Though the 33-year-old does sometimes recognizes she’s in a heightened state, Benny’s low-key presence can calm her. “It is helpful to have a partner that will understand where maybe the temperature is at, and meet you where you are,” Selena explains.

Timmy Throws Matt in Toilet

Oscar hopeful Timothée Chalamet is telling all on his stinky experience working with Matthew McConaughey! After wrapping their 2014 flick Interstellar, Timmy remembers feeling “very moved” and “sad to be leaving.” Then, “I went in my trailer and I went in the bathroom and there was a huge turd in my toilet,” the Marty Supreme star, 30, said, Variety reported. “I felt so disrespected.” After sleuthing to find out who on set “let it loose,” he determined the Serenity alum, 56, was behind the gross “souvenir.” “Matthew had this devilish grin on his face,” Chalamet shared. “I said, ‘Why did you do that?’ And he said, ‘It’s a Texas coming of age, baby.’ ”

Kaley Pricked by Thorny Rose

Being the new girl on the set of Charmed wasn’t easy for Kaley Cuoco. “You’ve got Alyssa Milano, Rose McGowan and Holly Marie Combs. I’ve never met them,” she recently recalled to Dax Shepard on the Armchair Expert podcast of joining the supernatural TV show’s cast in season 8 in 2005. “I am so freaking nervous.” But the Big Bang Theory alum, 40, alleges Rose, 52, made the experience worse by being less than welcoming! “I still don’t know if she liked me. I don’t know,” Kaley told Shepard. “I was terrified.” While the Flight Attendant star acknowledges it was “weird” for her to suddenly integrate into an already close-knit crew, she suspects there might have been more at play with the Scream star’s cold shoulder. “I was super-hot,” shares Kaley. “I don’t think that helped.”

Christina Dumped Hollywood’s Hottest Hunk

Married … With Children alum Christina Applegate admits she wasn’t very impressed by Brad Pitt back in the ’80s — in fact, she “dumped” him mid-date! Part of the same friend group, the actress invited the actor to join her at the 1989 MTV Video Music Awards, where she was set to present, but then spent the whole night ogling Skid Row rocker Sebastian Bach. “I left with Sebastian,” the Dead to Me star, 54, spills in her new memoir You with the Sad Eyes, according to Page Six. “And it gets worse: Brad was left to sullenly drive my mom … home.” As Christina tells it, Brad, 62, was “very mad” and continued to hold a grudge for years.

Dax Reveals Abuse Details

It’s been a decade since Dax Shepard first revealed he was molested as a child, but the Parenthood alum is releasing a memoir that shares disturbing new details of the abuse. The 51-year-old says it took him “four months” to rehash the trauma on paper. “And I was pretty emotional during the few months,” he shared on his Armchair Expert podcast. “I was having really weird, kind of, spikes of emotions and moodiness, and I would forget that’s why I was having that. But I finished it, and something about it existing there feels like a lot of weight is off my shoulders.” The podcaster and husband of actress Kristen Bell was only 7 when an 18-year-old neighbor initiated the inappropriate contact — and Dax long blamed himself. “I’m like, ‘It’s my fault, and I’m gay, I must have manifested this because I’m secretly gay,’ ” he recalls. “I had all these insane thoughts for 11 years or 12 years.”

Valerie’s Childhood Assault Horror

Valerie Bertinelli has been hiding a dark secret from childhood. “I was sexually assaulted,” reveals the One Day at a Time star. “I’m pissed off that it happened. Nobody deserves that.” According to Val, 65, the shocking abuse occurred when she was just an 11-year-old who loved reading, playing with Barbies and riding her bike. “The very first time I said it out loud to my therapist, I thought, ‘I’m going to feel better now,’” she said in an interview with People. “It got worse before it got better.” Her long-repressed trauma manifested itself in body shame and self-criticism. “When you stop eating things for comfort, stop drinking alcohol, it exposes your feelings. You can deal with them or not,” Valerie says. “And I chose to deal with them.”
