KIM & KOURTNEY KARDASHIAN
Length of feud: Hours
Anyone who's ever seen an episode of Keeping Up with the Kardashians knows E!'s most famous family is also its most temperamental. In January, Kim and Kourtney butted heads over motherhood, with Kim, who would later welcome a daughter of her own, criticizing Kourtney for her "boring and miserable" life. Though heated, the argument was resolved by episode's end, and fast-forward to the future, Kourtney was at Kim's side when she got engaged to Kanye West.

KIM & KYLE RICHARDS
Length of feud: 3 years, on-and-off
Life in the limelight has not helped the relationship between the Real Housewives of Beverly Hills stars, who in their first season on the Bravo show got into a screaming match that resulted in Kim accusing Kyle of stealing her home. Since then, the two have faced more ups and downs navigating their strained sisterhood, especially as Kim struggled with alcoholism, but for the time being, it appears all is well. "We're probably the closest we've maybe ever been," Kim told PEOPLE in January.

LIAM & NOEL GALLAGHER
Length of feud: 4 years and counting
There's never a dull moment between the brothers Gallagher, whose most recent dust-up began as a result of Noel's decision to leave Oasis in 2009. "I've got nothing to say to him. Not interested in the slightest right now," Liam said in a June radio interview, admitting he doesn't even have Noel's phone number. "It's not like Noel's knocking at my door with a box of chocolates and a bunch of flowers going, 'Speak to me,' and I'm going, 'No.' We're just not getting on at the moment."

MADONNA & CHRISTOPHER CICCONE
Length of feud: 5 years
A onetime member of his sister's inner circle, Christopher served as everything from Madonna's assistant to the artistic director of her 1993 Girlie Show tour. But that all changed with the release of his 2008 tell-all, Life with My Sister Madonna, in which he dished on her relationship with ex-husband Guy Ritchie, among other things. The siblings stopped speaking, but Christopher told the Huffington Post in December 2012 they've since reconciled. "We are back to being a brother and sister," he said, though admitted, "It's not completely there yet. We are not fully back. It will never be that."

ERIC & JULIA ROBERTS
Length of feud: 10 years
Making their way in Hollywood as aspiring actors in the 1980s, the Robertses were a tight-knit pair, but a 2001 article in Britain's The Independent newspaper revealed that the two had not spoken in 10 years. "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 told The Daily Beast in 2010. "We stopped talking and then with the birth of [her twins Hazel and Phinnaeus in 2004] we started talking again."

OLIVIA DE HAVILLAND & JOAN FONTAINE
Length of feud: 70 years and counting
If you need a lesson in holding a grudge, look no further than sisters Olivia and Joan, who have been at odds with one another for nearly a century. In 1942, both sisters were nominated for a Best Actress Oscar and it was the younger Joan who brought one home for her role in Alfred Hitchcock's Suspicion, a part Olivia reportedly coveted. Five years later, when Olivia was awarded her own statuette for To Each His Own, her sister reportedly attempted to give her a congratulatory handshake backstage but was shunned. As recently as 2008, the two have refused to appear in the same room, when they were both invited to a special Oscar party marking the 100th anniversary of Bette Davis's birth.
