7 Celebrity Sibling Feuds That Are Too Nasty to Forget

It's a brother and a sister kind of thing.

National Sibling Day is April 10, so what better way to celebrate it than talk about all the celebrity siblings who hate each other? So tender.

Hollywood is chock-full of notorious celebrity sibling feuds, from Kim and Rob Kardashian’s social media spat to Madonna’s ice war with her brother Christopher Ciccone. Hell, the blood-relative riffs date back to Olivia de Havilland and Joan Fontaine’s Academy Awards shade. A-list siblings have hated each other since the dawn of time.

These seven feuds are the nastiest of the bunch. Relive them below, and take comfort knowing things will never get this bad with her mooch-off brother.

  • Kim and Rob Kardashian

    Kim has historically been hard on Rob, as documented on their E! show Keeping Up with the Kardashians. Her tough-love approach toward Rob’s weight gain (and reported depression) seemed harsh compared to sister Khloe’s kinder disposition. Things between Kim and Rob escalated in March 2015 when the brother posted a photo to Instagram of Amy from Gone Girl on Instagram and captioned it, “This is my sister Kim. The bitch from Gone Girl.” Rob later deleted the post, but that didn’t stop Kim from throwing shade at Rob in her July 2015 interview with Rolling Stone. “Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes,” Kim told the glossy. RS asked if she thinks “it’s not more like hookers and meth at the Ritz,” to which she responded, “No no. Or he’d be skinny.” Burn. However, by August 2015, the two ended their beef.

  • Madonna and Christopher Ciccone

    Once upon a time, Madonna and Christopher were thick as thieves. At one point, Christopher was Madonna’s assistant and even served as the artistic director for her 1993 Girlie Show World Tour. But things took a nosedive in 2008 when Christopher released an explosive tell-all, Life with My Sister Madonna, which included sordid details about Madge’s marriage to Guy Ritchie. An ice war ensued, but the two patched things up by 2012. “We are back to being a brother and sister,” he told The Huffington Post. “It’s not completely there yet. We are not fully back. It will never be that.”

  • Eric and Julia Roberts

    Eric and Julia were tight until Eric developed substance abuse issues and broke up with his longtime girlfriend Kelly Cunningham. Julia betrayed her brother and took Kelly’s side. (She helped Kelly gain custody of her and Eric’s daughter.) This led to a riff that lasted a decade, but Eric and Julia patched things up when Julia gave birth to her twins in 2004. “We’re brother and sister and we both have really strong opinions about things, so it’s a lot of ’f– you,’ ’no, f– you’ and hanging up the phone. But it got so blown out of proportion,” Eric dished in 2010 to The Daily Beast. “We stopped talking and then with the birth of [her twins Hazel and Phinnaeus in 2004] we started talking again.”

  • The Jonas Brothers

    They were pop’s favorite trio–until they abruptly called off their 2013 tour two days before opening night. The reason? They were bickering about everything from music direction to video treatments. Middle brother Kevin revealed in January 2015 the brothers had terrible “friction” and that dissolving their professional relationship saved their family.

  • Michael and Jermaine Jackson

    According to MadameNoire.com, Jermaine was fed up with Michael’s king complex during his Bad era, so he penned a diss track in protest. It was titled “Word to the Badd”–subtle, we know. Jermaine reportedly hoped the track would help MJ get a grip on reality. Of course, this is just one of many chapters in the Jackson sibling dysfunction book.

  • Kyle and Kim Richards

    These Real Housewives of Beverly Hills vets are perhaps the most volatile siblings on television. Why? (Typically) Kim’s antics. The most iconic spat between these two was when Kim accused Kyle of stealing her house. Here’s hoping these two can kiss and make up for good.

  • Olivia de Havilland and Joan Fontaine

    The Business Insider reports Olivia and Joan were neck-and-neck about everything, from acting roles to gentlemen suitors. Their tension reached a fever pitch at the 1942 Academy Awards: Both ladies were up for Best Actress, with Joan eventually winning over Olivia. Olivia apparently didn’t congratulate Joan afterwards, which was cold AF–but not as cold as what went down in 1975. Joan put Olivia on blast for not contacting her when their mother died. Olivia’s response? Joan was probably too busy at the time to care. ZING. Their fight lasted 40 years.
